Bestfriend's Sister [kim mingyu]

Meeting you again

Mingyu sat at his desk, the glow of his laptop illuminating the darkened dorm room. His notes sprawled chaotically across the table, mirroring the chaos in his mind. College life wasn't the smooth path everyone had promised.

"Just get into SNU," they said.

"Life will be set." Those words now felt like a cruel joke.

Surrounded by prodigies and overachievers, he often wondered if he truly belonged. Balancing academics, friendships, and the rare moments of self-care had become an exhausting juggling act.

And just when he thought it couldn't get more complicated, fate threw him a curveball.

At the 2024 fresher's party, amidst the crowd of enthusiastic new faces, his heart froze. There she was—his crush. The girl who had unknowingly stolen his heart years ago now stood a few feet away, laughing effortlessly with a group of freshmen. Mingyu's pulse quickened as a wave of disbelief washed over him.

"What is she doing here?" he muttered under his breath. For years, he'd assumed she would follow her brother's footsteps and study abroad. Her brother—his best friend—had often talked about how their family prioritized prestigious overseas education. Seeing her here, in his university, was the last thing Mingyu expected. It wasn't just her presence that threw him off. It was the tangled web of emotions that came with it.

Mingyu had long accepted that his feelings for her were off-limits. She wasn't just any girl; she was his best friend's sister. And if there was one unspoken rule in his life, it was this: never break the bro code.

He could already hear his friend's voice in his head, joking yet firm: "You even think about my sister, and I'll kill you, dude." It wasn't an actual threat—probably—but Mingyu had never dared to test it. Yet, seeing her now, radiant and completely unaware of the storm she'd just stirred in his heart, made things infinitely harder. As the evening wore on, he tried to act normal. To blend into the crowd. But his eyes kept drifting back to her. She looked different—not the high schooler he remembered but someone more confident, more vibrant. 

"Why now? Why here?" he thought. Life was already overwhelming, and now he had to deal with this? But deep down, he knew the truth. He wasn't mad because she was here. He was mad because, for the first time, he couldn't ignore the possibility of something more. And that scared him more than failing his next midterm.

"Eoh? Mingyu oppa?" Sera's voice broke through the noise of the crowded room. Her eyes lit up as she smiled at him, her face the perfect blend of surprise and warmth.

"It's been so long, right?" Mingyu froze for a moment, caught off guard by how effortlessly she drew his attention. Rubbing the back of his neck—a nervous habit he couldn't seem to shake—he managed a coy smile.

"Yeah, it has," he replied, his voice quieter than he intended. A brief silence settled between them, the kind that felt heavier than it should. Mingyu scrambled for something to say, anything to fill the growing gap. "Congrats," he finally offered, his tone sincere. "Getting into SNU's med school isn't easy. You must've worked really hard."

"Thank you, oppa." Sera's smile widened, her cheeks slightly tinged with pink.

Before either of them could say more, a loud voice cut through the moment. "SERA-YAH!" Her friends were calling from the other side of the party, their laughter and energy adding to the lively chaos of the party. Sera glanced over her shoulder before turning back to Mingyu.

"I think they're waiting for you," Mingyu said, his tone gentle but his expression unreadable. She hesitated for a moment, as if weighing whether to stay or go. "You're right. I'll see you later, oppa," she said with a small nod before heading toward her friends.

Mingyu watched her retreating figure, her laughter blending into the noise of the party. He sighed and ran a hand through his hair again, the familiar ache in his chest returning.

Some weeks later

"Bro, let's win this game," Joo Hyuk said, clapping Mingyu on the shoulder, his eyes brimming with determination.

"Yeah, let's do this!" Mingyu replied, his voice full of energy as he tightened his shoelaces and jogged onto the field.

The match between SNU's engineering department and the medicine department had drawn a sizable crowd, the atmosphere electric with cheers and chants. From the whistle's blow, it was clear this wasn't going to be an easy game. Both teams played fiercely, each pass and tackle charged with adrenaline.

It was neck-and-neck, the score tied until the final moments. Then, with a perfectly timed pass from Joo Hyuk, Mingyu seized the opportunity. With a sharp kick, the ball soared past the goalkeeper and into the net.

The engineering department erupted into cheers, their players rushing to huddle around Mingyu, who was grinning ear to ear. "We did it!" he shouted, his voice barely audible over the roar of celebration.

On the sidelines, Sera watched the scene unfold with a smile. The medicine department's supporters were quieter now, some already drifting toward the exit. She turned to her friends and laughed lightly, saying, "I guess we'll have to cheer a lot louder for our medicine department next time."

Mingyu, still catching his breath, heard her words over the noise. He glanced toward her, his grin softening. Her laugh, her effortless charm.

It wasn't the words that caught him off guard but her outfit — her cheerleading outfit. 

The way the uniform fit her, or how the vibrant red skirt clung to her thighs, drawing his eyes in an almost magnetic pull. It was the sheer presence she exuded from across the field that captivated him.

Mingyu had always been aware of her beauty, under the stadium lights, she was a vision that sent a rush of heat through him. Every leap, every sway of her hips was a siren call, pulling him in deeper despite the distance.

He gulped hard, trying to focus on the other celebrating their victory, but distraction had a way of creeping in when least expected. Mingyu felt an undeniable pressure building within him, an urgency that demanded his attention. "Oh shit, not now," he muttered under his breath, realizing he couldn't ignore the undeniable reaction his body was having any longer. The heat radiating from his cheeks was felt in more than just his face.

He excused himself, the camaraderie of his teammates drowning in the chaos of his thoughts as he slipped away towards the washroom. Once inside, he swiftly closed the door behind him, locking it with an almost desperate urgency. The small space was eerily quiet, but in the stillness, the rush of blood in his ears was deafening.

With shaky hands, he fumbled with his pants, feeling the strain of his arousal pressing tightly against the fabric. The image of Sera in that unforgettable outfit - the way it hugged her curves, the glimpses of her pale skin - played behind his eyelids. It was intoxicating, igniting a fire within him that was impossible to suppress.

As he freed himself, his breath quickened, the need to release the tension almost overwhelming. He thought of her laughter, the way she sparkled with energy, and the sight of her moving gracefully with each cheer. Each thought sent shivers through him, and he couldn't help but quicken his pace.

Mingyu leaned against the cool tiles of the wall, consumed by the moment, lost in his mind as the outside world faded away. In that tiny sanctuary, he allowed himself to indulge in the fantasy, letting the image of Sera dance across his thoughts, a vibrant whirl of red and gold that pushed him closer to the edge.
