Chapter 1 – A Glance That Changed Everything
The library was quiet that late afternoon, the kind of silence that wrapped around the shelves like a blanket. Jun had always liked it that way—still, orderly, predictable. He sat at his usual corner desk, sketching absentminded lines in his notebook instead of reading the thick literature book in front of him.
And then—he looked up.
The boy who walked in wasn’t someone Jun had ever seen before. Tall, with soft brown hair that fell into his eyes, and an air of calm that made the silence around him feel deeper. He looked lost for a second, scanning the shelves as if searching for something—or maybe someone.
Their eyes met.
It lasted less than a heartbeat, but for Jun, it was as if the entire library had disappeared. The fluorescent lights dimmed, the ticking clock vanished, and only those eyes—dark, sharp, and strangely tender—remained.
Jun’s chest tightened. His pencil froze mid-stroke. He had never believed in love at first sight. But right now? Right now he wasn’t so sure.
The boy, Eunwoo, tilted his head slightly, acknowledging Jun’s stare with a faint curve of his lips. And then he walked past, toward the shelves at the back.
Jun let out a breath he hadn’t realized he was holding. His heart was beating far too fast for such a small moment.
Something about that glance—it wasn’t just attraction. It was a pull.
Like gravity itself had shifted and decided: You belong to him.

Chapter 2 – Names in the Quiet
The next day, Jun returned to the library earlier than usual. He told himself it was for studying, but his restless glances at the entrance betrayed him.
When Eunwoo appeared again, carrying a stack of books, Jun felt heat creep up his neck.
Eunwoo noticed him almost instantly. Instead of heading to the far shelves, he walked straight to Jun’s table.
“Is this seat taken?”
Jun shook his head quickly, trying to appear calm, though his palms were damp.
“I’m Eunwoo,” the boy said, placing his books down. His voice was smooth, unhurried.
“Jun,” he managed to reply.
For a while, they read in silence. But Jun found it impossible to focus. Every time Eunwoo shifted, every time he turned a page, Jun’s eyes darted toward him.
And Eunwoo—Jun didn’t notice at first, but Eunwoo was watching him too.
Not casually. Not like one might glance at a stranger.
His gaze lingered, heavy and thoughtful, as if he were memorizing every line of Jun’s face.
When Jun finally caught him staring, Eunwoo didn’t look away. Instead, he smiled, a quiet, knowing smile that made Jun’s heart stumble.

Chapter 3 – The First Thread of Obsession
By the third meeting, it was no longer coincidence.
Jun arrived to find Eunwoo already waiting at the same table, an untouched book open in front of him.
“You’re late,” Eunwoo said lightly, as if they had agreed to meet.
Jun blinked, startled. “I—I didn’t know we had a time.”
Eunwoo leaned forward, resting his chin on his hand. “Then let’s say we do, from now on.”
It was bold. Too bold for someone he barely knew. Yet Jun couldn’t bring himself to refuse.
He nodded, feeling the invisible thread between them tighten.
That day, Eunwoo asked questions—simple ones at first: favorite books, favorite colors, hobbies. But the way he listened was intense, like every word Jun spoke was precious.
And when Jun laughed at one of Eunwoo’s dry comments, Eunwoo’s expression softened in a way that made Jun’s chest ache.
It was too soon. Too sudden. Too much.
But as Eunwoo walked beside him when they left the library, Jun realized something frightening:
He didn’t want the thread to loosen.
And Eunwoo—he was already thinking, quietly, firmly—I won’t let it loosen. Ever.
Part 2 – Sweetness with Shadows
Chapter 4 – The Unshakable Presence
Jun had never been the type to let people close so easily. He liked his quiet, his small routines, the comfort of solitude. Yet somehow, Eunwoo had slipped into his life like a shadow that never left.
Every day after classes, Jun found him waiting outside the library. Sometimes leaning casually against the wall, sometimes sitting on the bench with that unreadable smile.
“You’re late again,” Eunwoo teased one evening.
Jun rolled his eyes, trying to hide the flutter in his chest. “I had class.”
Eunwoo stood and fell into step beside him. “Then I’ll walk you home.”
It was such a simple statement, but it made Jun’s pulse skip. He wanted to protest—We barely know each other—but the warmth of Eunwoo’s presence silenced him.
When they reached Jun’s apartment building, Eunwoo didn’t ask to come inside. He just looked at him for a long, lingering moment.
“See you tomorrow, Jun.”
And with that, he walked away, leaving Jun at the door with a strange ache in his chest.

Chapter 5 – Sweetness in Small Things
Eunwoo started noticing the little things.
If Jun forgot his pen in class, Eunwoo handed him one before he even asked.
If Jun skipped breakfast, Eunwoo would silently slide a snack bar across the table.
If Jun looked tired, Eunwoo would tilt his head and murmur, “Get some sleep tonight, alright?”
Jun wanted to laugh at how attentive Eunwoo was—but instead, he found himself smiling shyly, cheeks warming.
One afternoon, Jun sneezed while flipping through a book. Without hesitation, Eunwoo pulled a tissue from his pocket and held it out.
“You… carry tissues?” Jun asked, laughing.
Eunwoo shrugged. “I figured you might need them one day.”
It was ridiculous. Sweet. Ridiculously sweet.
And yet—there was something in Eunwoo’s gaze when he said it. Something too sharp, too certain, as if he had planned for Jun’s every move.

Chapter 6 – The First Hint of Possession
Jun didn’t notice it right away.
But slowly, Eunwoo’s sweetness carried weight.
When Jun talked too long with his classmates after lecture, Eunwoo appeared at his side, placing a gentle hand on his shoulder. His voice was calm, but his eyes weren’t.
“Let’s go.”
When Jun mentioned a new friend inviting him to study together, Eunwoo’s lips curved into a smile that didn’t quite reach his eyes.
“You don’t need anyone else. You already have me.”
Jun laughed it off at first. He’s just joking… right?
But that night, lying in bed, he replayed Eunwoo’s words in his head. The tone. The weight behind them.
He wasn’t sure if it was scary or comforting. Maybe both.
Because the truth was—Jun didn’t want Eunwoo to leave. Not ever.
And Eunwoo, watching him from across the library the next day, thought the same thing.
You’re mine already. You just don’t realize it yet.

Part 3 – Dangerously Sweet
Chapter 7 – A Gentle Cage
Jun was used to walking home alone. Yet lately, he never had the chance—Eunwoo was always there, waiting.
“Don’t you have anything better to do?” Jun teased one evening, adjusting his bag.
Eunwoo’s reply was simple. “No. You’re all I need to do.”
Jun froze. It wasn’t just the words—it was the quiet sincerity in them. The way Eunwoo said it like a promise, like a vow.
They walked side by side in silence, the city lights flickering above them. Eunwoo’s hand brushed against Jun’s, and before Jun could react, Eunwoo caught it gently.
Jun tried to pull back. “People will see—”
“Let them,” Eunwoo whispered, tightening his grip. “I don’t care. You’re mine.”
His words should have scared Jun. But instead, his heart fluttered wildly, traitorously, as if it had been waiting to hear those words all along.

Chapter 8 – Sweetness That Binds
It was the little things that made Jun realize he was already wrapped in Eunwoo’s world.
Whenever he opened his locker, there was always something inside—his favorite chocolate, a note written in neat handwriting, sometimes even a sketch of him reading.
Jun blushed every time, half embarrassed, half touched.
One day, when he confronted Eunwoo, the taller boy just smiled lazily.
“You like it, don’t you?”
Jun wanted to deny it. He wanted to roll his eyes and act annoyed. But his lips betrayed him, curving into a small smile.
“…Yes.”
Eunwoo’s gaze darkened, soft but heavy. “Then I’ll never stop.”
---
Chapter 9 – The Edge of Obsession
It wasn’t all sweetness.
Jun noticed that Eunwoo hated when others got too close. If a classmate leaned in too much during group projects, Eunwoo’s jaw would tighten. If someone laughed with Jun for too long, Eunwoo’s hand would slip around Jun’s chair, pulling him subtly closer.
One evening, when Jun bumped into an old friend outside a café, Eunwoo’s smile was polite—but his fingers dug into Jun’s wrist just enough to leave a mark.
Later, as they walked home, Eunwoo’s voice was soft but firm.
“Don’t let anyone else touch you like that.”
Jun frowned, tugging at his wrist. “He’s just a friend.”
“I don’t care,” Eunwoo said, stopping in his tracks. His eyes gleamed under the streetlight, dangerous and tender all at once. “I don’t share.”
For a long moment, Jun’s breath caught in his throat.
And then, instead of pulling away, he whispered, “Okay.”
Because deep down, he liked it—being wanted this much. Being claimed.

Part 4 – First Cracks of Love
Chapter 10 – A Subtle Surrender
Jun had always thought of himself as independent, someone who didn’t need anyone to guide his steps. Yet, more and more, he found himself adjusting his pace to match Eunwoo’s.
It wasn’t deliberate at first—just small things. Waiting an extra second so they could walk together. Choosing the seat by the window in the cafeteria because Eunwoo liked it. Holding back sharp words because he didn’t want to see that fleeting hurt in Eunwoo’s eyes.
It hit him one afternoon in the library. He had been working quietly on his essay, sunlight slanting through the window, when he felt a shadow fall across his desk.
“Move over,” Eunwoo whispered, sliding into the seat beside him as if it were his rightful place.
Jun opened his mouth to protest—but before he could, Eunwoo rested his chin on Jun’s shoulder, eyes drifting over his notes.
Jun stiffened, heat rushing to his cheeks. “Y–You’re too close.”
Eunwoo’s voice was low, dangerous and sweet. “Not close enough.”
Jun’s hand tightened around his pen. He should’ve pushed him away, should’ve reminded him that this was a public space. But instead, he leaned back just slightly, enough that Eunwoo’s warmth seeped into him like sunlight through glass.
And for the first time, Jun admitted silently to himself—he didn’t want distance anymore.

Chapter 11 – The World Against Them
The closeness wasn’t unnoticed.
Classmates whispered. Some envied Jun; others mocked him behind his back. A few even warned him, telling him Eunwoo was “too intense” or “strange.”
Jun pretended not to care. But when he overheard someone sneer, “He’s just a toy Eunwoo will throw away,” something inside him twisted painfully.
Later, Eunwoo found him brooding by the vending machines.
“Jun,” he called softly.
Jun turned, his voice sharper than he intended. “Do you ever think about what people say? About us?”
Eunwoo tilted his head, unfazed. “Why should I?”
“Because—because it matters!” Jun snapped. But even as he said it, the words felt hollow.
Eunwoo stepped closer, caging Jun against the machine. His eyes burned with quiet intensity. “The only thing that matters is you. I don’t need anyone else’s approval. Do you?”
Jun opened his mouth, then closed it. His chest ached, his resolve cracking like thin ice.
“…No,” he whispered.
Eunwoo’s expression softened instantly. He reached up, brushing Jun’s cheek with the back of his fingers. “Good. Because I don’t share you with the world, Jun. You’re only mine.”
Jun’s heart pounded wildly, and for once, he didn’t argue.

Chapter 12 – Threads of Tenderness
For all his sharp possessiveness, Eunwoo had a way of beingFor all his sharp possessiveness, Eunwoo had a way of being unexpectedly gentle.
When Jun caught a cold one chilly morning, Eunwoo showed up at his door with soup, medicine, and a scowl that looked more like worry.
“You should’ve told me,” Eunwoo muttered, fussing over him.
Jun, wrapped in a blanket and sneezing miserably, tried to glare. “You’re not my mom.”
“No,” Eunwoo said quietly, tucking the blanket tighter around him, “but I want to take care of you.”
Jun’s throat tightened, his eyes stinging unexpectedly. No one had ever said that to him before,
Part 5 – When Obsession Turns to Love
Chapter 14 – The Unspoken Bond
The days that followed carried a strange softness. Jun had expected himself to feel suffocated by Eunwoo’s constant presence, but instead, he found himself searching for it.
It was in the way Eunwoo appeared at his side during class breaks, casually handing him a bottle of water without asking. In the way Eunwoo’s hand brushed against his when they walked together—just enough to send sparks through Jun’s skin.
And in the quiet moments when Jun caught Eunwoo staring, his gaze no longer wild but full of something deeper, something steady.
“Why do you always look at me like that?” Jun asked one afternoon, trying to sound annoyed, though his heart wasn’t in it.
Eunwoo’s lips curved into a half-smile. “Because you’re mine.”
Jun rolled his eyes, but his ears turned red. “You sound like a villain from some drama.”
“Maybe I am,” Eunwoo teased, leaning closer. “But you still stay.”
Jun opened his mouth to retort, but nothing came out. Because it was true. He did stay. He wanted to stay.
And that realization both terrified and thrilled him.

Chapter 15 – The Date That Wasn’t
It started innocently.
“Come with me this weekend,” Eunwoo said suddenly, as they packed their bags after class.
Jun blinked. “Where?”
“You’ll see.”
Jun should’ve refused. He had homework, responsibilities, a hundred excuses. But when Eunwoo looked at him with those sharp eyes, softened just for him, Jun found himself nodding.
That Saturday, Eunwoo appeared at his door, dressed in casual jeans and a white shirt, hair falling neatly over his forehead. Jun stared for a moment longer than he should have, before muttering, “You look… decent.”
“Decent?” Eunwoo smirked. “You mean handsome.”
“Don’t push it.”
They ended up at a small amusement park on the edge of town. Jun was startled—he had expected a café, a walk, maybe a bookstore. Not roller coasters and cotton candy.
But as the day went on, something strange happened.
Jun laughed.
Really laughed, the kind that left his stomach aching and his eyes watering. He laughed when Eunwoo screamed louder than him on the ferris wheel, when Eunwoo insisted on winning him a stuffed bear at the ring toss and failed miserably five times before finally succeeding, triumphant like a child.
Jun hugged the bear to his chest, hiding his smile. “You’re ridiculous.”
“And you’re smiling,” Eunwoo shot back, eyes gleaming.
Jun froze for a heartbeat, then looked away. “…Maybe.”
That night, as they walked home under the streetlights, Jun felt something shift inside him. The weight of obsession was still there—but beneath it, love was blooming.

Chapter 16 – Cracks in the Armor
Not everything was perfect.
Eunwoo’s possessiveness still flared, sharp and unsettling. When a classmate leaned too close to Jun during a group project, Eunwoo’s glare was so intense the boy stumbled over his words and quickly backed away.
Later, Jun confronted him.
“You can’t keep doing that,” he said firmly.
Eunwoo crossed his arms, expression dark. “He was touching you.”
“He was pointing at the paper!” Jun groaned.
“I don’t like anyone near you,” Eunwoo admitted, voice low, almost trembling. “I know it’s selfish. But I can’t—Jun, I can’t stand the thought of losing you.”
Jun’s anger softened. He had expected defensiveness, denial—but Eunwoo’s voice cracked with something raw, something vulnerable.
Slowly, Jun stepped closer, placing a hand on Eunwoo’s chest. “You’re not going to lose me.”
Eunwoo froze, eyes wide.
Jun gave him a small, almost shy smile. “But you have to trust me. Trust that I’m not going anywhere.”
For the first time, Eunwoo didn’t argue. He just pulled Jun into his arms, holding him like he was the only anchor in a storm.
And Jun let him.

Chapter 17 – A Confession Under the Stars
It happened on a quiet night. They had sneaked onto the rooftop of the school, the city lights flickering in the distance.
Jun lay back on the cool concrete, staring at the stars. Eunwoo sat beside him, his gaze not on the sky, but on Jun. Always on Jun.
“Do you ever think about the future?” Jun asked softly.
Eunwoo tilted his head. “Only if you’re in it.”
Jun’s heart skipped. He turned his face away, but Eunwoo caught his chin gently, making him meet his eyes.
“Jun,” Eunwoo whispered, voice trembling with sincerity. “I know I’m selfish. I know I scare you sometimes. But I… I love you.”
The words hung in the air, heavy and fragile.
Jun’s breath caught. He had known, of course. From the beginning, from the first obsessive gaze, he had known. But hearing it aloud—it was different.
“I…” Jun hesitated, his chest tight. He wasn’t good with feelings. He had always been cautious, guarded. But looking at Eunwoo now, at the raw desperation and tenderness in his eyes, something inside him broke free.
“I love you too,” Jun said, voice barely above a whisper.
Eunwoo’s eyes widened. For a moment, he looked like he couldn’t believe it. Then, slowly, a smile spread across his face—soft, radiant, unlike anything Jun had ever seen.
He leaned down, and their lips met.
It wasn’t wild, or possessive, or desperate. It was gentle. Sweet.
The kind of kiss that spoke of promises, not chains.
And in that moment, Jun realized: Eunwoo’s obsession had become love. And Jun had chosen to accept it.
---
Chapter 18 – Only Us
After that night, everything shifted.
They still argued, still teased, still had moments where Eunwoo’s jealousy flared. But there was trust now, and a bond neither could deny.
Jun found himself seeking Eunwoo’s touch, his presence, his smile. He found comfort in the way Eunwoo’s hand fit perfectly with his, in the way his laughter sounded when Jun teased him back.
And Eunwoo, though still fiercely protective, softened in ways Jun never imagined. He listened more. He learned to step back, to trust Jun’s words.
One evening, as they sat on the rooftop again, Jun leaned his head on Eunwoo’s shoulder.
“You know,” Jun murmured, “I used to think you were terrifying.”
“I was,” Eunwoo admitted, chuckling softly. “I still am, sometimes.”
Jun smiled, eyes fluttering shut. “But now… you’re just mine.”
Eunwoo’s heart swelled, and he pressed a kiss to Jun’s hair.
“Always.”
And as the stars glimmered above them, Jun realized something:
This love wasn’t perfect. It was messy, obsessive, frightening at times.
But it was real.
And it was theirs.
