In Leon's office
The heavy curtains remained closed, shutting out the outside world, while the dimness of the office was gently broken only by the flickering light of the candelabras. At the center of the room, atop a massive table that could easily host a banquet, rested an impressive scale model of Mondstadt at a 1:10,000 ratio. Every tile, every rooftop, every tower had been meticulously reproduced, as if the city itself had been shrunken and imprisoned there under the watchful eye of its master.
Leon sat before the model, his chin resting on his hand, observing it with a cold and calculating expression, like a god contemplating his creation.
Suddenly, without warning or permission, the office door opened with a sharp crack.
The intruder couldn't be seen—at least, not immediately—but the sound of high heels rhythmically striking the marble floor filled the silence.
"You've finally arrived... Stop causing trouble," Leon muttered without even turning around.
His eyebrow arched subtly when he felt a soft, familiar pressure against his back. A pair of invisible hands slid around his neck, embracing him from behind, while a gust of warm air caressed his right ear, sending an involuntary shiver down his spine.
But it didn't stop there.
The invisible fingers began to toy with the buttons of his shirt, undoing them one by one with malicious patience, as if wanting to strip away not only his clothes but also his composure.
"I said... stop causing trouble." Leon's voice sounded harsher, yet still serene, like someone scolding a mischievous pet.
Without even looking, he moved with absolute precision: his right hand firmly grabbed the invisible wrist, while his left slid to the intruder's neck and squeezed with firm, decisive strength.
With a swift and ruthless motion, Leon lifted her and tossed her onto the nearby sofa without any ceremony.
If it had been any other member of his family, he would never have been so rude… but with her? She was the exception. The only one.
And, as always, the ruder he was... the more satisfied she became.
"Ha… haha… You're still as incredible as ever, Your Highness… mm~" Yelan's voice sounded, letting out a moan mixed with pain and pleasure.
Leon simply sighed, running a hand through his hair as he watched her. The invisibility cloak slid off the woman's shoulders, revealing her slender and powerful silhouette. Her blue hair gleamed in the dim light, and the smile on her lips was one of pure euphoria… and adoration.
Even as she massaged her neck, where his finger marks had surely already begun to appear, Yelan wore that satisfied smile, as if she were treasuring that moment as a private trophy.
"Did you get the information I asked for?" Leon asked bluntly.
"But of course…" Yelan replied, gliding gracefully over to him and pulling a stack of documents from her storage bracelet, like a magician pulling rabbits out of a hat. "It's all here, ready for Your Highness~"
Leon waved dismissively, rejecting the offer without even glancing at the papers.
"I don't want to read that now."
"Okay, okay… Your Highness is so lazy…" Yelan giggled softly, completely used to that posture of indifferent superiority that both fascinated… and excited her.
Without asking permission, she approached the model, picking up the tiny pieces representing soldiers, civilians, and nobles. With agile and elegant movements, she began positioning them at strategic points around the miniature city.
As she did so, she meticulously narrated each movement, each routine.
"This one… leaves at seven in the morning and returns at eight at night… this other one… visits the guild headquarters every Tuesday and Thursday…"
Her voice was as sharp as it was seductive, mixing efficiency and provocation in equal measure.
Leon crossed his legs, observing her while mentally recording every detail. Internally, he couldn't help but applaud her efficiency. As always… impeccable.
As expected of her.
So professional… so devoted…
In fact, much of his success—the fall of the Lawrences, the destruction of the Gunnhildrs—all of it bore Yelan's invisible fingerprints. The woman who, like a shadow, infiltrated where no one else could, so that he, even from afar, would know everything.
She was his eyes. His blade. His most faithful devotee.
"What do you think, Your Highness?" Yelan asked, with that eager look of someone who only wants to please.
"Very useful. Now my plan is foolproof." Leon replied, with that cold tone that thrilled her so much. "Even though I want to destroy and rebuild… I don't desire civilian bloodshed."
As he spoke, he adjusted the final details in his mind, now fueled by the precise information she had brought.
Yelan tilted her head, smiling, completely enchanted.
"Your plan is still as… crazy and domineering as ever." She bit her lower lip, a gleam of excitement in her eyes. "Following you was… definitely the best choice. You haven't given me even ten hours of boredom since I gave myself to you."
She moved even closer, until she was just inches from Leon.
Her hands gently cupped his cheeks, pulling his face closer, as if wanting to mark her territory.
But suddenly, her expression changed.
Satisfaction gave way to sudden irritation, like a spoiled child realizing she didn't receive all the attention she deserved.
"But… that said, Your Highness…" Her voice softened, but there was venom hidden beneath the honey. "What was that about last time?"
"Huh? What are you talking about?" Leon frowned, confused.
Yelan's hands squeezed his cheeks tighter, as if she wanted to force the answer out of him.
"You… asked me to approach Esdeath." Her voice was now low, but loaded with passionate indignation.
Leon let out a brief, indifferent laugh.
"And what's the problem with that?"
Leon blinked slowly, tilting his head, puzzled.
(They're a sadist and a masochist... Wouldn't that be a perfect match?) he thought, letting out a silent sigh. (What's wrong with letting them satisfy each other?)
"The problem is huge," Yelan retorted, her gaze full of disgust.
"Hmm?" Leon arched a brow, intrigued.
"After trying for a while… I realized: Esdeath and I have the worst compatibility possible. Seriously, I've never felt so much pain in such a… boring way. It wasn't pleasant at all," she replied with an expression of frustration and contempt.
Leon let out a restrained laugh, leaning back in his chair with his typical carefree air.
"Even if you say that… I still can't understand what goes on in your heads—sadists, masochists…" He shrugged, with a resigned look. "I mean… Esdeath, I get. But you… Yelan… your kink is on another level."
Yelan let out an exaggerated huff and, without ceremony, sat directly on Leon's lap, crossing her legs as if it were her throne.
"That woman is worthless, not one bit!" she exclaimed, pouting. "She just wanted to have fun… didn't care for my mood even for a second. We have the worst compatibility." She crossed her arms, visibly annoyed.
Leon watched, shaking his head with an ironic smile.
"You're more demanding about this than I thought… Sorry, but I can't—and don't want to—understand any of that."
His expression became complex, as if torn between fascination and total ignorance of that world of desires and perversions.
On the outside, Yelan was the cold, skilled, lethal woman everyone knew. But inside… an incorrigible masochist, completely surrendered to the pleasure of pain. And, above all, devoted to him.
"So… what do you want?" Leon asked, though he already knew the answer.
Yelan smiled, leaning in and caressing his chin with delicate fingers, her eyes shining with desire and devotion.
"Do I really need to explain?" She tilted her head with irresistible charm. "The only person in this world who can satisfy me… is you." Her voice carried a silent, almost religious reverence. "And since I made such a great contribution this time…" She raised five fingers, licking her lips provocatively. "I want to add five more hours than usual to our session."
Leon massaged his temples, letting out a tired sigh.
"…Yelan… sometimes I seriously worry about accidentally killing you."
Yelan giggled mischievously, leaning in even closer, as if his words were the sweetest of promises.
"Ah… don't worry, Your Highness," she whispered, almost in a moan. "I would never resent you."
Leon let out a dry laugh.
"Haha… I think not only wouldn't you hate me… you'd probably ascend to heaven happily." He gave her a firm smack on the butt. "Get up."
"Huh?" Yelan widened her eyes in surprise. "You're coming now?"
"Let's go, you pervert…" Leon rolled his eyes, with that irresistibly superior look. "Didn't even notice you're still bleeding?"
Yelan's expression softened, but the masochistic gleam didn't leave her eyes. In fact, it seemed even more intense.
This infiltration mission in Mondstadt had been especially dangerous. Even for a master like her, it had left marks—including a deep sword wound on her back. Though she tried to hide it, Leon had already noticed: the metallic scent of blood mixed with her body's unique fragrance.
"Please pay more attention to your safety," he said firmly.
"Don't worry…" Yelan replied, unconcerned, with that provocative smile. "I'm not going to die from an attack of this level. Such a small wound…" She closed her eyes and bit her lower lip. "…only gives me pleasure."
Leon snorted, frustrated, but also unable to suppress a slight smile.
"You said I'm the only one who can satisfy you, right? Then don't be greedy, Yelan. As long as you come back alive, I'll… personally make sure to satisfy you, even if I don't like that crazy kink of yours."
He gave her a pat on the head, both scolding and protecting her at the same time.
Then, he pulled down the zipper of Yelan's tight leather outfit, revealing part of her marked and wounded skin. With a swift gesture, he grabbed some alcohol from his storage compartment and, without the slightest ceremony, began disinfecting the wound.
Yelan bit her lip hard, taking a deep breath as her body involuntarily tensed, caught between surprise, pain… and pleasure.
Yelan wrapped her arms around Leon as she spoke:
"Haha… You're the only one in this world allowed to make me feel pain, right?"
"Exactly… You understand everything so well."
Leon snorted, pushing her face away with two fingers.
"Hmph. Whatever… But if you die accidentally, it would be a great loss for me."
Yelan smiled, satisfied, running her hand across his chest.
"Is it possible that Your Highness… is a tsundere?"
Leon widened his eyes, a vein popping on his forehead, but he just sighed and stood up.
"Yelan… prepare your mind… and your body for me tonight." His voice was cold, dominant. "I'll make you completely… taste my skills."
Before she could answer, he gave her a loud, hard smack on the butt, eliciting from her a moan mixed with pain and ecstasy.
Yelan's smile widened, surrendered, completely devoted to the man to whom she had given her body and soul.

"Hmph. If you really want to be useful, then entertain me, try to throw those pathetic power stones at me. Let's see if even your insolence can amuse a king."
