Synopsis: In a lively classroom, you sit next to Kim Mingyu, a classmate shrouded in rumors of being just a pretty face. As you work together on a project, Mingyu’s goofy charm draws you in, and he secretly falls for your kindness. After baking your favorite pastry and receiving your enthusiastic praise, he gains the confidence to shine in a competition, realizing that the true victory lies in the warmth and connection you share.

The classroom buzzed with a comforting, familiar warmth. It wasn’t the heat from the sun streaming through the large windows, nor was it the quiet hum of conversations filling the air. It was something else, something softer. The warmth that came from the people inside it, from shared laughter and the sense that, here, everything was okay. You sat at your desk, tapping your pen idly against your notebook, catching a glimpse of Kim Mingyu out of the corner of your eye.

Mingyu.

If someone asked what you thought about him, you’d probably just shrug and say he was a classmate. That was it. But to everyone else, he was something more. There were whispers about him, as there always seemed to be—gossip and rumors that didn’t quite line up with the boy who sat next to you every day. The athletes around school scoffed at his abilities, some calling him a pretty face, someone who relied on his looks rather than skill. And there was always that undercurrent, the sense that people thought he was cocky, full of himself.

But the Mingyu sitting next to you? He was none of those things. He was goofy, with that boyish charm, always cracking jokes even when they didn’t land. He had this unassuming kindness about him, offering his help when no one asked, showing up when people least expected it.

You treated him like he was just Mingyu. No superstar, no pedestal. You didn’t buy into the gossip because the guy who stumbled over his words sometimes and grinned like a kid when he made a lame pun didn’t fit any of those narratives.

And maybe that’s why, out of all the noise around him, he gravitated toward you.

For Mingyu, you weren’t just a classmate. You were something safe, something steady. In a world where people seemed to have made up their minds about him, you were the exception. Your laugh, your feisty remarks, and the way you lit up a room—it all drew him in like a magnet. He felt the weight lift off his shoulders when he was near you, the pressure to be someone else fading away.

When the teacher announced the group project, calling out pairs, your name followed by his, Mingyu felt a spark of excitement flare up inside him. You glanced his way with a grin, and that was all it took for him to feel like the luckiest guy in the room.

You met at a cozy café after school, surrounded by the scent of fresh pastries and the sound of low chatter. The light streaming in through the windows caught in your hair, and Mingyu found himself distracted as you spoke. You were talking about the project, gesturing animatedly as you explained an idea, but he was too focused on the way you seemed so at ease.

Then he saw it—the smile that spread across your face as you grabbed a pain au chocolat from the plate in front of you, your eyes lighting up with pure joy as you took a bite.

“Oh my God, this is so good!” you said, your voice full of delight. You looked like you had just discovered the world’s greatest treasure in that flaky, chocolate-filled pastry, and Mingyu couldn’t tear his eyes away.

It was in that moment, sitting in a quiet café with you, that something shifted inside him. Your smile was like sunlight, warm and inviting, and it hit him all at once—he wanted to see that smile every day.

He wanted to be the reason for it.

That night, Mingyu couldn’t get the image of you out of his head. He found himself standing in his kitchen, sleeves rolled up, determined to bake. It was a mess. Flour everywhere, chocolate smeared on the counter, and more than a few failed attempts at recreating the pain au chocolat you loved so much. But after hours of trial and error, he finally made a batch that didn’t look half bad.

The next morning, he walked into class carrying a tray of pastries, his heart racing with a nervous energy he wasn’t used to. He handed them out to everyone, trying to act casual, but when he gave you yours, he watched you like a hawk, waiting for your reaction.

You took a bite, your face lighting up instantly. “Mingyu!” you exclaimed, eyes wide. “This is so good, I could die happy!!!”

Your voice carried across the room, loud and dramatic, and Mingyu couldn’t help but laugh. You were always so expressive, so full of life, and it made his heart swell. The other classmates joined in, complimenting him, but your reaction was the only one he cared about. He tried to play it cool, but the grin on his face was too big to hide.

The pastries worked their magic, not just on you, but on the whole class. People started seeing Mingyu differently. They smiled more, joked with him, and slowly, the whispers about him being cocky faded away. He was just Mingyu to them now, too.

But it was the day of his big competition that everything changed.

Mingyu stood on the field, the weight of all the past rumors pressing down on him. He could feel the eyes on him, the doubts lingering in the air. He was stuck in his own head, anxiety creeping in, when suddenly, a voice broke through the noise.

“MINGYUUUUUUU!”

It was you. He looked up, spotting you in the stands, your hands cupped around your mouth as you yelled his name. You weren’t just cheering—you were cheering for him, your voice full of excitement and encouragement. It was like a jolt of electricity through his system, and for a second, everything else faded away. The people, the pressure, the expectations—it all disappeared, leaving just the sound of your voice and the warmth it brought.

His classmates joined in, shouting his name, the support filling the air. And suddenly, Mingyu felt lighter. Like he could do anything.

When he crossed the finish line, winning first place, it wasn’t just about the victory. It was about you, the one who believed in him even when he wasn’t sure he believed in himself. Without thinking, he ran to you, sweeping you up into his arms in the tightest hug he’d ever given anyone. His heart was racing, but not from the competition—from the pure happiness that surged through him.

His classmates rushed over, teasing him as they pulled both of you into a giant group hug. He was red-faced, embarrassed by their teasing, but he didn’t care. He was happy. Giddy, even.

And as he looked down at you, still wrapped in his arms, he realized something: it wasn’t just the competition he had won today. It was you. You were his victory, his warmth in the details of everyday life.

You Can't Get Rid Of Me

Pairing : Kim Mingyu x Reader

Genre : Angst, Slightly Suggestive

Warnings : Mentions of murder and running away

Having your marriage arranged by your parents, your boyfriend thinks that it's best to part ways but you're not ready to give up on what you both have.

"Y/n, it's best if we break up. Trust me, I don't want this either but you know your parents. They will kill us for sure," Mingyu's voice was barely a whisper but his words pierced through your ears. You chest tightens for a second.

"So? You're asking me to marry the old man?" you ask.

"If I can, I'll marry you right now, Y/n. It's just........ impossible," his reply makes you fume.

In a flash, you had him pinned down against the couch, with your hands placed on the soft material beside his head. Your legs trapped his own ones. Mingyu's face was flushed red and he looked away from you.

Tears brimmed in your eyes as you speak, "I can run away the night before the wedding or I can poison the old man the next time he comes to visit. My parents won't bother looking for me because afterwards I'll be a disgrace to the family. Even if you don't do anything, at least have some faith in our relationship like I do," droplets of angry tears fall on his face.

Mingyu flinches, the guilt of hurting you heavy in his chest.

"I'm sorry, Y/n. I promise I won't make you cry ever again. I'll- I'll marry you. We'll get away from this horrible place where we aren't allowed to love"

A small smile forms on your lips. You lean in and press your lips against his. Instantly, all you worries were washed away.

Mingyu doesn't take too long to kiss you back. He cups your face with his large hands and presses back harder, gently biting your lower lip in the process. You grip his hair and it makes him groan.

You pull away and stare at him, "Don't think you can get rid of me easily, Kim Mingyu. Whether you like it or not, I'm your future wife"

Mingyu grins cheekily, despite his flushed face.

"Seems like I'm stuck with you"
