Chapter 1 - Chapter 1: The System Awakens

The alarm screamed at 6:30 AM, dragging Yuki from a dreamless sleep. His hand shot out from under the covers, fumbling across the nightstand until his fingers found his phone and silenced the noise. He'd fallen asleep with his glasses on again—the frames had left faint red grooves across the bridge of his nose.

Yuki sat up slowly, blinking sleep from his eyes. Pale morning sunlight filtered through his curtains, casting long shadows across his small bedroom. His reflection in the mirror across from his bed caught his attention: light orange hair sticking up at odd angles, large hazel eyes still unfocused with sleep, the oversized sleep shirt that had twisted around his torso during the night making him look smaller than he actually was.

He looked like he'd been electrocuted.

Another day, he thought, stretching his arms above his head until his shoulders popped. The October air was cold enough that he could see his breath misting faintly. He really needed to ask the landlord about the heating again.

From the kitchen, he heard the familiar sounds of his mother preparing breakfast—the clink of dishes, the soft rush of running water, her humming something off-key that might have been a J-pop song from last decade. She'd already be in her scrubs, hair tied back in a practical ponytail, moving through her morning routine with the efficiency of someone who'd done it a thousand times.

Yuki grabbed his glasses from the nightstand, slid them on, and padded toward the bathroom. The apartment was small—just two bedrooms, one bathroom, a kitchen that barely fit a table for two—but it was home. His father paid for it from overseas where he ran his company, sent money every month like clockwork. His mother worked at the hospital because she wanted to, because helping people made her happy in a way that money alone never could.

They were busy. They were often absent. But they loved him in their own distracted way, and Yuki had long since made peace with that.

The bathroom was freezing. Yuki turned on the shower, twisted the dial to lukewarm—not quite cold, not quite hot, just enough to wake him up without shocking his system. While he waited for the water to heat up, he brushed his teeth, staring at his reflection in the mirror above the sink.

His hair had grown longer. It fell past his shoulders now in natural waves, the light orange color striking even in the dim bathroom light. People always asked if he dyed it. He'd stopped bothering to explain that no, it was completely natural, inherited from some distant relative on his father's side. Let them think what they wanted.

The shower was quick and methodical. Wash hair, condition, soap, rinse. He'd perfected the routine to exactly seven minutes—long enough to get clean, short enough not to waste water or time. When he stepped out, the mirror was fogged over, which was fine. He didn't need to see himself to get dressed.

Back in his room, Yuki pulled on his school uniform: white button-up shirt, dark slacks, the blazer he'd leave unzipped because the school's heating was usually too aggressive. Over everything, he added his favorite oversized grey hoodie. Technically against dress code, but most teachers had stopped commenting on it after the first month of the school year. It was comfortable, warm, and made him feel less exposed when walking through crowded hallways.

He adjusted his glasses, ran his fingers through his damp hair to tame it into something resembling order, and headed for the kitchen.

"Yuki! Good morning!" His mother smiled when he appeared in the doorway. She'd already set out breakfast—rice, miso soup, grilled fish, a small plate of pickled vegetables. More food than she usually had time to prepare on a weekday. "I had a few extra minutes this morning, so I made your favorite."

"Thanks, Mom." Yuki slid into his seat, picking up his chopsticks. The fish was perfectly grilled, crispy on the outside, tender inside. "You didn't have to do all this."

"I wanted to." She sat across from him, cupping her own bowl of soup between her hands. Dark circles shadowed her eyes—she'd probably worked a late shift yesterday—but her smile was genuine. "How's school going? You haven't mentioned it in a while."

"It's fine. Same as always." Yuki took a bite of rice. "We're starting a new unit in chemistry. organic chemistry."

"That sounds complicated."

"Not really. its just bonds, they are simple once you understand the basics."

His mother's smile softened. "You make everything sound simple. Your teachers must love you."

Yuki shrugged, focusing on his food. His teachers did seem to like him, mostly because he turned in assignments on time, never caused trouble, and maintained grades in the top five percent of his year. It wasn't that difficult—school came naturally to him, always had. He just listened during lectures, took good notes, and did the work.

They ate in comfortable silence for a few minutes. His mother scrolled through her phone, occasionally showing him pictures from the hospital—a garden one of the nurses maintained, a patient's thank-you card, a group photo from someone's birthday celebration. Normal things. Safe conversation.

"I have a long shift today," she said eventually, finishing her soup. "Won't be back until late. There's curry in the fridge if you want it for dinner, or money in the jar if you'd rather order something."

"I'll probably just have instant ramen." Yuki collected both their dishes, carrying them to the sink. "Don't worry about me."

"I always worry about you." She stood, smoothing down her scrubs. "That's my real job."

She crossed to him, reaching up—he was taller than her now, had been since sophomore year though that was not a flex—and gently fixed his collar where it had folded wrong. Her hand lingered for just a moment on his shoulder.

"Have a good day at school, okay? And Yuki..." She hesitated. "You know you can talk to me about anything, right? If something's bothering you, or if someone's giving you trouble—"

"I'm fine, Mom. Really." He gave her what he hoped was a reassuring smile. "School's easy. No one bothers me."

It was mostly true. People didn't bother him so much as they didn't quite know what to do with him. The misgendering happened regularly—"excuse me, miss," followed by flustered apologies when he politely corrected them. His appearance confused people. His quiet nature made them uncertain. But no one was cruel about it. Most students just left him alone, which was exactly how he preferred it. peace

"Alright." His mother kissed his forehead, grabbed her bag, and headed for the door. "Love you!"

"Love you too."

The door clicked shut, and Yuki was alone. He finished washing the dishes, wiped down the table, and checked the time. 7:20 AM. He had plenty of time before school started, but he preferred leaving early. The morning streets were quieter, less crowded, easier to navigate without constantly dodging clusters of people.

He packed his school bag carefully: textbooks arranged by size, notebooks color-coded by subject, pencil case tucked into the front pocket. His current novel—a fantasy story about a hero who could manipulate time—went on top where he could reach it easily. He was three chapters from the end and wanted to finish it during lunch.

Yuki pulled on his shoes, grabbed his bag, and locked the apartment door behind him.

The Walk to School

The October morning air was crisp and clean, carrying the scent of fallen leaves and distant rain. Yuki kept his hood up and his hands in his pockets, his breath misting in front of his face. The streets were relatively empty—a few salarymen rushing toward the station, a elderly woman sweeping the sidewalk in front of her shop, a delivery truck making its rounds.

No one paid attention to him. It was peaceful.

Yuki pulled out his novel as he walked, reading while keeping one eye on the sidewalk ahead. The protagonist had just discovered that his time manipulation powers were slowly killing him—dramatic, if a bit predictable. Still, the author's prose was good enough that Yuki kept turning pages.

"Yo! Nakamura-san!"

Yuki's eyes flicked up from his book. Tanaka was jogging toward him from a side street, uniform rumpled like he'd thrown it on five minutes ago, hair sticking up in every direction.

"Morning, Tanaka-san." Yuki bookmarked his page and slipped the novel into his bag.

"Man, you're up early!" Tanaka fell into step beside him, grinning broadly. "I barely made it out the door. My alarm didn't go off, and my mom had to literally drag me out of bed. What's your secret?"

"I just wake up at the same time every day."

"Boring!" Tanaka laughed, completely unbothered by his own comment. "You should live a little, you know? Sleep in sometimes, skip first period, go get breakfast at that new crepe place instead."

"I'd rather not fail chemistry."

"You couldn't fail chemistry if you tried. You're like, stupid smart. No—wait, that came out wrong. You're really smart. Top of the class smart." Tanaka bumped his shoulder against Yuki's in what was probably meant to be a friendly gesture. "Seriously, you should tutor me sometime. I'm drowning in math right now."

"You could ask during lunch." Yuki adjusted his glasses. "I usually finish eating pretty quickly."

"Really? You'd help me?" Tanaka's grin widened. "Man, you're the best, Yuki-chan!"

"I'm male, Tanaka-san."

"What? Oh, right, yeah, I know. Sorry, it just slips out sometimes." Tanaka rubbed the back of his neck, looking genuinely apologetic. "You don't look like a Yuki-kun, you know? You're too pretty for that. More like a Yuki-chan. Or maybe Yuki-tan? That's cuter."

Yuki said nothing. This was familiar territory—Tanaka meant well, genuinely didn't understand why gendering him correctly mattered. Arguing about it would just make things awkward, and Tanaka would forget the conversation by tomorrow anyway.

"Anyway," Tanaka continued, apparently taking Yuki's silence as agreement, "you coming to the school festival planning meeting next week? Student council wants input from each class about what events we're doing."

"Probably not. I don't really do festivals."

"Come on! It's our last year of high school! You've gotta participate at least once." Tanaka threw an arm around Yuki's shoulders. "We could do a maid cafe! Or a haunted house! Or—wait, hear me out—a host club. Like in that anime. You'd be perfect for it!"

"I think I'll pass."

"Your loss, man." Tanaka finally released him as they approached the school gates. "Alright, I gotta run—need to copy someone's homework before homeroom. See you later, Yuki-chan!"

He sprinted off before Yuki could correct him again.

Yuki pulled his hood down, walking through the gates and into the main courtyard. The school building loomed ahead, three stories of concrete and glass, already half-full of students despite the early hour. Club activities, studying, socializing—everyone had their reasons for arriving before the first bell.

The entrance was crowded. Yuki navigated through the clusters of students, keeping to the edges, making himself small and unobtrusive. A group of girls near the lockers glanced his way, whispered something to each other, then looked away giggling. He ignored it.

The stairs to the third floor were less crowded. Yuki took them two at a time, his bag bouncing against his hip.

"Oh! Excuse me!"

A girl appeared around the corner, arms loaded with papers. She wasn't watching where she was going. Neither was Yuki.

They collided. Papers exploded everywhere like startled birds.

"I'm so sorry!" The girl immediately dropped to her knees, scrambling to gather the scattered sheets. "I'm such a klutz, I should've been paying attention—"

"It's okay." Yuki knelt beside her, helping collect papers. They looked like handouts for some class or club. "Accidents happen."

"Still, I—" The girl looked up at him. Her eyes went wide. "Oh. Oh wow. You're really pretty! Are you a first year? I haven't seen you around before."

Yuki's hands paused for just a moment. "Third year. Nakamura Yuki, class 3-B."

"Third year?" The girl blinked rapidly, her face slowly turning red. "Wait. You're... oh no. You're a guy, aren't you? Oh my god, I'm so sorry! I didn't mean to— That was so rude of me, I just assumed—"

"It happens a lot." Yuki handed her the papers he'd collected, standing up. "Don't worry about it."

"I'm still really sorry." She clutched the papers to her chest, looking mortified. "And thank you. For helping with these. You're really nice."

Yuki nodded and continued up the stairs. Behind him, he heard the girl's friend asking what happened, followed by frantic whispered explanations.

By the time he reached the third floor, his face felt slightly warm. Not from embarrassment—he was long past being embarrassed by mistaken identity—just from the attention. He preferred going unnoticed but it was ok from time to time.

Class 3-B was mostly empty. Yuki made his way to his usual seat in the back corner by the window, dropped his bag on the desk, and pulled out his novel. Twenty minutes until homeroom. Enough time to finish another couple of chapters.

The classroom gradually filled. Students trickled in alone or in groups, voices rising in volume, the familiar chaos of a school morning building around him. Yuki kept his eyes on his book, letting the noise wash over him without really listening.

"Nakamura-kun?"

Yuki looked up. Sato stood beside his desk, textbook in hand, looking hesitant.

"Morning, Sato-san."

"Sorry to bother you, but..." Sato opened his textbook to a marked page. "Yesterday's math homework. Problem seven. I got completely lost halfway through. Could you explain it?"

"Sure." Yuki set his novel aside, pulling out his own math notebook. "The trick is rearranging it into standard form first. See this? You need to move all the terms to one side before applying the formula."

He walked Sato through the steps, showing his work. Sato's expression shifted from confused to understanding, and by the end he was nodding enthusiastically.

"That makes so much more sense! I was trying to factor it directly, but the numbers weren't working out." Sato beamed at him. "Thank you so much, Nakamura-kun! You're a lifesaver!"

"No problem. Good luck with the rest."

Sato returned to his seat looking significantly less stressed. Yuki went back to his novel, but he'd lost his place and had to skim backward to figure out where he'd been.

"Alright everyone, settle down!" Kojima-sensei swept into the classroom, her perpetually harried expression already in place. "We have a lot to cover today. Attendance first."

She started calling names. Yuki waited, following along in his head.

"Nakamura Yuki-kun."

"Here."

The morning classes passed in familiar routine. Japanese literature involved analyzing symbolism in a Soseki short story—Yuki had thoughts about the teacher's interpretation but kept them to himself. Math was derivatives, which he'd already worked through last night. Chemistry was fun, exactly as interesting as he'd told his mother it would be.

Yuki took notes diligently, his handwriting small and precise, filling pages with information he'd probably remember even without writing it down. His mind wandered occasionally—thinking about his novel, wondering what he'd have for dinner, idly watching clouds drift past the window—but he always pulled his attention back before missing anything important.

The lunch bell rang at 12:30 PM.

Immediately, the classroom exploded into activity. Students pushed desks together, forming clusters. Bento boxes appeared. Conversations erupted. The social hierarchy of high school lunch reasserted itself with the efficiency of long practice.

Yuki pulled out his convenience store onigiri and his novel. The desk beside him remained empty—it usually did. He was fine with that.

"Nakamura-kun!"

Tanaka appeared out of nowhere, dropping into the empty seat. "So about that tutoring..."

"You're serious?" Yuki set his novel aside.

"Dead serious. I'm gonna fail the next math test if I don't figure this stuff out." Tanaka pulled out his homework, which was covered in erased attempts and increasingly desperate scribbles. "Help me, Obi-Wan Kenobi. You're my only hope."

Despite himself, Yuki smiled slightly. "Let me see what i can do young padwan."

They worked through the problems together. Tanaka was actually trying, which made it easier. He wasn't stupid, just impatient and prone to skipping steps he thought were obvious. Yuki showed him how to slow down, work methodically, check his answers before moving on.

By the time the warning bell rang for fifth period, Tanaka had successfully completed three problems on his own.

"Yes! I actually get it now!" Tanaka pumped his fist in the air. "Yuki-chan, you're amazing! I'm buying you lunch tomorrow to say thanks!"

"You don't have to—"

"No, seriously, I insist! What do you like? Curry? Ramen? Katsudon?" Tanaka was already planning, counting on his fingers. "There's that new place near the station that everyone's talking about. We should go there!"

"...Curry is fine."

"Curry it is!" Tanaka clapped him on the shoulder and headed back to his own desk, looking energized.

Yuki picked up his novel, but fifth period started before he could read more than a paragraph.

Physical Education

Fifth period was PE. Swimming.

The locker room was chaos—twenty teenage boys in various states of undress, shoving clothes into lockers, roughhousing, shouting across the room about weekend plans and video games. Yuki changed quickly in the corner, facing the wall, moving with practiced efficiency. Swim trunks, goggles, towel.

His reflection in the small mirror near the sinks caught his attention briefly. His body was thin, perhaps too thin—ribs visible, shoulders narrow, waist defined. No real muscle definition despite three years of mandatory PE. He'd always been like this, no height and no mass, metabolism too fast to ever gain weight.

"Yo, Nakamura! You coming?"

Yuki grabbed his goggles and headed to the pool.

The water was cold. Perfect. He slipped in gratefully, letting it cover him, the chill shocking his system awake. They were divided into groups by ability—Yuki was in the middle tier, decent enough not to embarrass himself but not good enough to stand out.

"Alright, everyone! Four laps freestyle, then two laps backstroke!" Yamada-sensei blew his whistle. "Go!"

Yuki swam. The rhythm was meditative—breathe, stroke, turn, repeat. Water rushing past his ears, the burn in his shoulders and lungs, the satisfying flip at the wall before pushing off again. He wasn't fast, but he was consistent.

He surfaced after his fourth lap, gasping for air.

"...it's genuinely hard to remember sometimes, you know?"

Tanaka and his friends were clustered at the pool's edge, apparently taking a break.

"The hair especially. That can't be natural."

"I dunno, my cousin has weird hair color too. Genetic stuff is weird."

"Yeah, but still. It's unusual."

"Nakamura! Keep moving!" Yamada-sensei's whistle shrieked.

Yuki switched to backstroke. The ceiling tiles above blurred past, water filling his ears, muting the world. He finished his laps, climbed out of the pool, and grabbed his towel.

The locker room was steamy and loud. Yuki showered quickly, changed back into his uniform, and pulled his hoodie on over everything. His hair was darker when wet, plastered close to his skull. He looked different. Almost masculine. He knew the illusion would break as soon as it dried.

The rest of the day passed. More classes, more note-taking, more carefully not making eye contact with anyone who seemed like they might want to start a conversation. By the time the final bell rang at 3:15 PM, Yuki felt pleasantly tired—the good kind of tired that came from a full day of mild mental engagement and minimal social stress.

He packed his bag methodically and headed out.

Evening

The apartment was empty. Dark. Quiet.

Yuki turned on lights as he moved through, setting his bag by his desk, checking the fridge for dinner options. The curry his mother had mentioned looked good. He heated it up, ate while reading the last chapter of his novel, and felt mildly disappointed by the ending. The protagonist resolved everything too easily. Where was the consequence?

He washed his dish, took a quick shower—lukewarm again—and settled at his desk to tackle homework. Math was straightforward. Literature required an essay about symbolism that he finished in forty minutes. Chemistry was just memorization, which he'd never had trouble with.

By 8:30 PM, everything was complete.

His phone buzzed. A message from his mother: Long shift tonight. Don't wait up. Love you! ♥

He texted back: Okay. Love you too.

Yuki changed into sleep clothes, set his glasses on the nightstand, and climbed into bed. It was too early to sleep—barely 9 PM—but he was tired enough not to care. His eyes drifted closed.

He woke to wrongness.

Not a sound. Not movement. Just an overwhelming sensation of presence—like someone had walked into his room and was standing directly beside his bed.

His eyes snapped open.

Darkness. The familiar shapes of his furniture. His desk, bookshelf, closet door slightly ajar like always.

But the feeling remained, heavy and undeniable.

And then text appeared above his bed.

Not on a screen. Not projected from any device. Just there—glowing brilliant blue, three-dimensional letters hanging in the air like someone had carved them from solid light.

[◈ SYSTEM INITIALIZATION COMPLETE ◈]

[HOST IDENTIFIED: NAKAMURA YUKI]

[COMPATIBILITY ANALYSIS: OPTIMAL]

[SYNCHRONIZATION: 100%]

[WELCOME TO THE LUST SYSTEM]

Yuki sat up slowly, reaching for his glasses. He slid them on. The text remained, sharp and clear and definitely not a hallucination.

"...What are you?" His voice was calm. Curious.

[THE LUST SYSTEM IS A GROWTH-ORIENTED DEVELOPMENT PLATFORM DESIGNED TO FACILITATE SEXUAL CONFIDENCE, SOCIAL CAPABILITY, AND PERSONAL ACTUALIZATION IN COMPATIBLE HOSTS.]

[YOU HAVE BEEN SELECTED AS THE CURRENT HOST.]

[WOULD YOU LIKE TO VIEW THE TUTORIAL?]

Yuki blinked at the glowing text. This was like something out of a light novel. System interfaces, growth mechanics, game-like progression. He'd read dozens of stories with similar premises.

He'd just never expected to be in one.

"...Sure," he said. "Show me the tutorial."

[◈ LUST SYSTEM TUTORIAL ◈]

[The Lust System operates on quest completion, skill acquisition, and statistical growth. As the host, you will be assigned quests of varying difficulty and nature. Completing quests grants Experience Points (XP), currency (Lust Points), and sometimes unique rewards.]

[Your progression is measured through the following statistics:]

A new window appeared, replacing the previous text:

[◈ STATUS WINDOW ◈]

QUESTS: 0 Active

INVENTORY: Empty

Yuki studied the window. His stats were... interesting. High appeal and adaptability, low confidence and charm. Technique at zero made sense—he'd never even kissed anyone. The numbers felt oddly accurate. Man he loved elden ring

"What do I do with this?" he asked the empty air.

[The System will assign you quests. Complete them to grow stronger. Upon completing the Tutorial quests, you will unlock additional features including the System Store, Skill Tree, and many more]

[Are you ready to begin the Tutorial Phase?]

[YES] / [NO]

Yuki considered his options. He could say no. But something told him that the System wouldn't just disappear. And if this was really happening—if he genuinely had access to some kind of supernatural growth mechanism—then refusing seemed shortsighted.

Besides, he was curious.

"Yes."

[◈ TUTORIAL PHASE INITIATED ◈]

[QUEST 1 OF 10: SELF-ACCEPTANCE]

[OBJECTIVE: Examine your body in a mirror for 10 minutes. Identify three physical attributes you find genuinely attractive about yourself.]

[TIME LIMIT: 24 Hours]

**[REWARDS:] **

Charm Aura (Level 1) - Passive skill

100 XP

50 LP

[FAILURE PENALTY:]

[NOTE: Quest cannot be refused. Timer begins now.]

A countdown appeared in the corner of his vision: [23:59:47]

Yuki looked at the timer, then back at the quest description. "Mirror examination. Identify three attractive attributes."

It seemed simple enough. Almost too simple. But he supposed that was the point of a tutorial—start easy, build up gradually.

He got out of bed and walked to the bathroom, turning on the light. The mirror above the sink showed his reflection—light orange hair messy from sleep, eyes slightly tired behind his glasses.

The quest probably wanted more than this.

Yuki pulled off his sleep shirt, then his pants and underwear, until he was standing completely naked under the bathroom's fluorescent lights. The full-length mirror on the door reflected everything without mercy.

He studied himself objectively.

Thin build, narrow shoulders, defined waist. Long legs, pale skin, no real muscle definition. His face featured delicate bone structure, large hazel eyes, full lips. His light orange hair fell past his shoulders in natural waves.

This was what caused all the confusion. This was why people called him "pretty" instead of "handsome," why they defaulted to feminine terms before catching themselves.

But the quest wanted him to find three things he genuinely found attractive.

His hair. It was genuinely unusual—a natural warm orange-gold that caught light interestingly. Striking. Distinctive. In any manga or anime, this would mark him as a protagonist. Someone special.

His eyes. Large eyes were considered attractive across most cultures. And hazel was rare enough in Japan to be notable. They were expressive, clear, framed by long natural lashes.

His waist. The definition between his ribs and hips created a aesthetically pleasing ratio. Proportional, balanced, the kind of symmetry that artists aimed for in figure drawing.

Three attributes. Identified.

The timer hit zero.

[◈ QUEST COMPLETE ◈]

[Physical optimization in progress...]

Warmth suddenly bloomed in Yuki's chest—not painful, just present. It spread outward like he'd swallowed hot tea, tingling through his limbs, making his skin hypersensitive for several seconds. The sensation was strange but not unpleasant.

Then it faded to a subtle warmth beneath his skin.

[Optimization complete. Charm Aura is now active.]

[Tutorial Quest 2 will be assigned within 24 hours.]

[You may now access your Status Window, Inventory, and Quest Log at any time by mentally focusing on them.]

[Would you like a demonstration of the System Store?]

Yuki stared at the floating text, his mind processing rapidly. The warmth under his skin had settled into something almost comfortable now. He looked at his reflection—nothing appeared visibly different, but something felt changed. Subtle. Like the air around him had shifted texture.

"...Yes," he said. "Show me the Store."

A new window materialized:

[◈ SYSTEM STORE ◈]

CURRENT BALANCE: 50 LP

[TUTORIAL SECTION - LIMITED ACCESS]

CONSUMABLES:

Stamina Potion (Small) – 10 LP (Restores 20 Stamina immediately)

Confidence Boost (Temporary) – 25 LP (+5 Confidence for 1 hour)

Appeal Enhancement (Temporary) – 25 LP (+3 Appeal for 2 hours)

World Information (Locked) – ??? LP (Requires Divine Skill unlock)

NOTE: Full store access unlocked after Tutorial completion. Additional categories include: Skills, Abilities, Tools, Enhancements, and Special Items.

Yuki studied the options. The prices seemed reasonable relative to his current balance. The temporary boosts could be useful if he needed them for specific situations.

"This is really happening," he murmured, half to himself. "I have a game system. For... sex? ."

[Correct. Do you have any questions before the tutorial window closes?]

"Several." Yuki grabbed his clothes, getting dressed while he thought. "First, why me? What makes me a compatible host?"

[Host compatibility is determined by multiple factors including psychological profile, growth potential, and dimensional resonance. Specific selection criteria are classified.]

"Of course they are." Yuki pulled his shirt on. "What happens after I complete the tutorial?"

[Full system access unlocks, including:]

Divine Skill selection (Choose your primary ability)

Master, Grandmaster, Awakened, and Unique Skill slots

Advanced Store access

Path System (World-specific specialization options)

"And these quests..." Yuki put his glasses back on. "They're going to involve actual... sexual activities, aren't they?"

[Affirmative. Tutorial quests will progress gradually from basic confidence-building to physical intimacy. All activities must be consensual. The System does not force actions, but declining quests results in penalties.]

"So I can refuse."

[With consequences. Continued refusal will result in System removal and permanent stat penalties.]

Yuki nodded slowly. That seemed fair, in a harsh sort of way. The System offered power and growth, but demanded participation in return.

"One more question. Can other people see the System interface?"

[Negative. All System elements are visible only to you.]

"Good to know."

[Tutorial window closing in 10 seconds. Quest 2 will be assigned within 24 hours. Good luck, Host.]

The windows vanished, leaving Yuki alone in his bathroom. He looked at his reflection one final time—same face, same body, but now with an invisible aura of attraction emanating from him at all times.

Tomorrow at school would be interesting.

Yuki turned off the bathroom light and went back to bed. Despite everything that had just happened, he found himself surprisingly calm. Maybe it was shock. Maybe it was the natural adaptability that his stats claimed he had. Or maybe he was just too tired to properly freak out.

He pulled the covers up to his chin and closed his eyes.

A system. Quests. Skills I can't turn off. All focused on becoming more confident and sexually experienced.

Well, he thought drowsily, at least school won't be boring anymore.

Sleep claimed him within minutes.

When morning came, the Charm Aura would still be active.

And his carefully quiet life would begin to change in ways he couldn't yet imagine.
