Park Ji-hoon opened his eyes with great effort. His head felt as if it had been struck by a sledgehammer. The neon glow of the Seoul streetlights that usually illuminated his small apartment had been replaced by a soft morning sunlight, filtering through thin lavender silk curtains. The air felt different—fresher, sweeter. It was like the scent of wildflowers mixed with something sweet and feminine.
"Is this... a dream?" he muttered.
But the voice... it wasn't his. It was the voice of a woman. Soft, melodic, with a mature tone full of authority.
Ji-hoon sat up abruptly. His body felt heavy at the top, like two soft pillows swaying every time he moved. His right hand—slender, with perfectly manicured nails—immediately touched his chest.
"Oh, damn..."
His breasts. No, her breasts. They were large. Immensely large. M-Cup, at least. Heavy, full, and incredibly sensitive. His fingers brushed against that smooth skin, and an electric sensation instantly jolted through his entire body. His nipples hardened under the touch, and he felt a strange wave of heat in his lower abdomen.
His buttocks—good God, they felt round and firm, pressing against the silk mattress beneath him with a soft but steady pressure. His stomach was flat, with faint abdominal muscles felt under the smooth skin, but his hips were wide, forming a perfect curve that made him want to... cry?
Ji-hoon jumped out of bed. His legs were long and smooth, and he nearly stumbled because of this new body's balance. A large mirror on the wall—in a room that wasn't his, filled with mahogany furniture and luxurious curtains—showed a figure that made him freeze.
The woman... she... had long, wavy purple hair that fell to her waist like a living lavender waterfall. Sharp, dark purple eyes, naturally red full lips, and flawless milky-white skin. Her face was mature and beautiful, around 35 years old, with a refined aura radiating intelligence and sensuality. Her body was every man's dream: gravity-defying M-Cup breasts, a slender hourglass waist, sexy firm buttocks, and long legs that would make a catwalk model envious.
"This... isn't me," Ji-hoon whispered, his voice trembling. The woman's hand—his hand—touched the face in the mirror. "I am... Park Ji-hoon. 28 years old. An ordinary Korean man working as a programmer at a game company. Last night I came home late, it was raining hard, that truck... the crash..."
The last memory: a white light and a cold, system-like voice: "Transmigration successful. New Host: Lirael Vespera."
Ji-hoon—or now Lirael—collapsed to the floor. His smooth knees hit the soft carpet. "Is this a game world? Eternal Heroes: Harem Chronicles? The harem isekai game I used to play? The protagonist is an academy student who becomes the strongest hero, gathers a harem of beautiful girls, and fights the Demon Lord..."
But now, he wasn't a student. He was a professor. And this body... belonged to a single mother.
The bedroom door creaked open. "Mama! Are you awake already?"
A small 12-year-old girl skipped inside. Her hair was light purple, similar to Lirael's but shorter and cuter. Her eyes were large and innocent, her cheeks chubby. She hugged Lirael's waist tightly, her face pressed against those large breasts.
"Mama, today is the first day of the new semester at the Academy! Elara doesn't want to be late. You promised to teach me basic healing spells again!"
Ji-hoon froze. This child... Elara Vespera. Lirael's daughter. In the game, she was a minor NPC—a sweet professor's daughter who often appeared in side quests to help the protagonist learn healing magic. Now, this girl was calling him "Mama."
Ji-hoon, as a man, felt incredibly strange. This body was warm, the child's hug was soft, but his chest... his breasts were pressing against Elara's face, and the sensation made him deathly embarrassed. "U-uh... yes, honey. Mama... will be ready in a moment."
Lirael's voice came out automatically, soft and full of affection. The memories of this body began to flow: Lirael Vespera, Head Professor at the Arcana Eternia Academy, specializing in Elemental Magic and Advanced Combat Theory. A single mother since her husband—a legendary knight—died years ago fighting a demon invasion. She was respected, feared, and... desired by many.
Ji-hoon swallowed hard. "I have to survive. I am a man. I can't be weak. Even if this body... is insane."
He stood up, with Elara still clinging to him. "Mama, your hair is messy. Let Elara brush it."
The little girl climbed onto the bed, her small hands carefully brushing the long purple hair. Ji-hoon felt the touch—gentle and full of love. Something in Lirael's chest fluttered. It wasn't desire, but... an unfamiliar warmth. As a Korean man who lived alone, he had never felt this before.
Standing in front of the mirror again, Ji-hoon tried to adapt. He put on his professor's robes—elegant black with purple accents, which clung tightly to his chest and hips. Every movement made his breasts sway, and the magic bra (he didn't know what kind of magic it was) supporting them felt like a constant embrace. The long skirt swirled around his legs, and his buttocks... oh my, every step felt accidentally sexy.
"Why does this body have to be this... perfect?" he grumbled internally. "I don't want to fall in love with a man. I'm still Ji-hoon. My pride as a man cannot be lost."
But the body reacted on its own. When he touched his inner thigh while putting on stockings, a warm sensation rose to his lower abdomen. He bit his lip. "Focus. This is a game world. The protagonist, Rylan Storm, just entered this year as a transfer student. He'll become OP and gather a harem—beautiful mages, lady knights, elf archers, cute healers. But I... am his professor. I have to teach him? And... unbeknownst to me, in the game's hidden lore, Rylan has a MILF fetish. He likes mature, grown women."
Ji-hoon smiled cynically at the mirror. "Good. I'll keep my distance. I don't want to be part of that harem."
Elara tugged at his hand. "Mama, let's have breakfast! We'll walk to the academy together later."
They went down to the dining room of a luxury villa on the outskirts of Valoria—the capital of the Kingdom of Eldoria. This world was Elysium: a vast continent with kingdoms of humans, elves, dwarves, and beastkin. Magic flowed like air, but only 1 in 100 people had high affinity. The Arcana Eternia Academy was the center of it—a giant white stone fortress on a hill, with seven towers for each magic element: Fire, Water, Wind, Earth, Light, Dark, and Void. There were training arenas the size of football fields, a library with millions of spell books, and dormitories for thousands of students of all races.
Ji-hoon enjoyed breakfast—toast with crystal flower honey and refreshing herbal tea. Elara chatted cheerfully about her friends: "There's Mia the healer, she loves telling stories about monsters in the northern forest. And then there's Theo, a little swordsman who always loses his matches but never gives up!"
Side characters, Ji-hoon thought. In the game, they would become the protagonist's party members.
After breakfast, they boarded a magical carriage—pulled by a white unicorn. The streets of Valoria were busy: merchants peddling potions, adventurers returning from quests, beastkin children playing with small flames in their hands. Ji-hoon felt people's gazes. Men turned their heads, their eyes hungry. Women were envious or admiring. Lirael's body was indeed a magnet.
"I hate this," he muttered. But his male half... somewhat enjoyed it? No! He brushed the thought away.
Arriving at the academy gates, Elara waved and ran to her junior class. "Mama, pick me up later!"
Ji-hoon—as Prof. Lirael—walked to the faculty room. The corridors were full of first-year students: teenagers aged 16-18, in blue-black uniforms, carrying magic wands or practice swords. The atmosphere was full of excitement.
"Professor Vespera! Good morning!" greeted an elf girl with pointed ears and green hair. "Elemental Fusion class this morning is going to be exciting, right?"
Ji-hoon gave a professional smile. Lirael's memories helped him: "Yes, Miss Lira. We will combine fire and wind today. Don't forget the safety runes."
The Dean, an old man named Archmage Thorne—white hair, long beard—greeted him in the faculty room. "Lirael, you look... more glowing today. New semester stress?"
"Just a good rest, Dean," Ji-hoon replied, his voice automatically elegant.
Another fellow professor: Prof. Mira, a beautiful healer in her 40s with D-cup breasts (though far outmatched by Lirael), smiled slyly. "You're a busy single mother, but your body is always perfect. What's your secret? Do share."
Ji-hoon let out a small laugh. "Genetics, perhaps."
But internally: This woman... is she flirting? I'm not interested. I'm a man!
The first class began. The lecture hall was huge, with 200 students sitting in circular benches. Ji-hoon stood at the podium, his magic staff—elderwood with a purple crystal—glowing.
"Welcome to Advanced Magic Theory. I am Professor Lirael Vespera. Today, we discuss the basics of fusion spells. But remember, magic is not a toy. One mistake, and you could lose a hand."
He began to teach. His movements were graceful, his breasts swaying slightly as he pointed to the magical chalkboard. The male students in the front row swallowed hard. Ji-hoon was aware, but he ignored it. "Focus on the lesson, not my body."
In the middle row, a young man stared intensely. Rylan Storm. Messy black hair, sharp blue eyes, an athletic body from sword training. He was a transfer student from a border village, with S-rank affinity for all elements—the true protagonist. In the game, he would date 12 heroines, including princesses, succubi, and more.
But now, Rylan's eyes were fixed on Lirael. Not like an ordinary student. There was a fire there. Ji-hoon felt it—that gaze wasn't just ordinary admiration. It was... hunger. Like a man who knew exactly what he wanted: a mature, experienced woman with a body that could drive him crazy.
Ji-hoon shuddered. "Don't. I won't fall for it."
After class, students crowded around to ask questions. A cute little healer named Sophie asked about potions. "Prof, your breasts... uh, I mean, your magic aura is so strong!"
Comedy moment: Ji-hoon almost choked. "Thank you, Sophie. Regular practice."
Rylan approached last. "Professor Vespera. I'm Rylan Storm. I'm... interested in your class. Perhaps private tutoring sometime?"
Deep, confident voice. Ji-hoon felt his cheeks flush—this body was reacting. "We'll see about the schedule, Mr. Storm. Focus on the basics first."
Rylan gave a thin smile. "Very well, Professor. I look forward to it."
As Rylan left, Ji-hoon leaned against the table. "It's only the first day. I have to adapt. This body... is the greatest temptation. But I am Ji-hoon. I will save myself, maybe return to my original body, and... well, enjoy this adventure without becoming part of a harem."
But in a corner of his heart, something whispered: this body feels alive.
POV: Rylan Storm
I, Rylan Storm, have just moved to this academy. My small village was destroyed by a goblin horde, and I was the one who survived thanks to this strange power. S-rank affinity? I didn't even know what that meant back then. But now, in Professor Vespera's class...
Her. That woman.
Not the cute girls my age. Not slender elves or energetic beastkin. Lirael Vespera is... perfect. Tempting purple hair, eyes that can read your soul, a body that... good God. Those breasts, that waist, the buttocks that sway slowly as she walks. She's a single mother, they say. Mature. Experienced. I can imagine her teaching her child, but at night...
I've never told anyone, but since I was a child, I've liked women like that. MILF. A harsh word, but true. They know what they want. They don't play around. And this Professor... she has an aura of power. Her magic is strong, but there's a fragility in those purple eyes. Like a secret I want to uncover.
During class, I couldn't stop staring. When she leaned over slightly to write on the board, those breasts... moved. I was hard under the table. Damn. It's only the first day, but I already know: I must have her. Not as an ordinary harem member. As the primary one.
I smiled to myself in the corridor. "Professor Lirael... we're going to have plenty of time."
Ji-hoon went home that afternoon, with Elara by his side. The little girl talked about her first day: "I made a flower bloom with healing magic! But my friend Theo fell during sword practice."
Ji-hoon laughed. "You're wonderful, Elara."
Night fell. After bathing—an R18 moment: warm water flowing over smooth skin, hands soaping those large breasts, a sensation that made Ji-hoon bite his lip to hold back a moan—he lay in bed. The body was tired, but his mind was racing.
'I'm in a game world. I'm a professor. I have to teach the protagonist who's going to become a harem king. And he likes me. I have to keep my distance. But... why does it feel so interesting?'
Elara entered the room and climbed into bed. "Mama, tell me about Father."
Ji-hoon hugged her. "Someday, sweetheart."
That night, a dream came: Lirael's memories of her husband who died, and the image of Rylan smiling.
