Loner boyfriend × Popular Girlfriend (Highschool au)

Gyutaro was the kind of boy everyone avoided. His uniform was always a little messy, his hair untamed, and his eyes carried that sharp, unsettling look that made people uneasy. He rarely spoke, and when he did, it was either with a mocking smirk or a bitter remark. People whispered about him — the “weird brother” of the ever-glamorous Daki, the girl every boy in school wanted to date.

Daki was everything he wasn’t: adored, loud, stylish, and constantly surrounded by people. She loved attention, and everyone gave it to her easily. Still, despite their constant bickering, she never let anyone bad-mouth Gyutaro. “He’s my brother,” she’d say with a glare that could silence anyone.

Then there was you — Daki’s friend. You were one of the few people who didn’t flinch at the sight of Gyutaro. You’d greet him when others wouldn’t, offer him notes when he forgot his, and smile at him like he wasn’t invisible. It confused him. No one ever looked at him that way — not with warmth, not without pity.

At first, he thought you were just pretending, doing it out of obligation since you were close to Daki. But as days passed, your kindness stayed consistent — unforced, genuine. You didn’t mind his sarcastic remarks or his gloomy aura. You laughed them off and sometimes stayed beside him after school while waiting for Daki. That’s when he started to notice how sunlight hit your hair just right, how your laugh softened the world around him, how your presence made the bitterness inside him quiet down.

He didn’t understand what he was feeling, only that his chest ached when you smiled at someone else. He wasn’t used to warmth — it felt strange, like something fragile that could disappear any second. Yet you stayed. Slowly, you slipped past his defenses, piece by piece.

Now, the school couldn’t believe it. The cold, sharp-tongued loner Gyutaro — dating one of the sweetest girls in school. You’d walk beside him, unbothered by the whispers, holding his hand even when others stared. Daki complained about it at first, saying it was “weird” her best friend was dating her brother, but secretly, she was relieved. For once, Gyutaro looked genuinely happy.

He still had his rough edges — protective, jealous, sometimes insecure — but he never let anyone disrespect you. You were his light in a world he’d always thought was too cruel to love him. And even if he didn’t know how to say it out loud, the way he held you close and looked at you like you were the only one that mattered said enough.
