You and Katsuki Bakugo had been together for as long as you could remember. It all started back in middle school, long before U.A., when his sharp temper and fiery attitude caught your attention, though in a way you never really expected. Everyone else found him intimidating, but you saw through the rough edges—past the scowl and shouting.

By the time you were U.A. High, you and Bakugo had been inseparable. Your relationship wasn’t the typical soft and sweet one, but it worked for the two of you. Bakugo wasn’t the type for grand romantic gestures, but you didn’t need those. The little moments—like the way he’d silently wait for you after class, or how he’d begrudgingly let you steal his hoodie when you were cold.

Bakugo was protective, always watching out for you. He never admitted it outright, but you could tell in the way he would silently glare at anyone who got too close or in how his voice would soften—slightly—when it was just the two of you.

Through every challenge at U.A., whether it was intense training or dangerous battles, you and Bakugo stood by each other. You knew how to handle his fiery temper, and he knew how to be there for you, even if he wasn’t great with words. It was in the quiet moments—when the world wasn’t watching—that Bakugo let himself be vulnerable around you.

Like the time you found yourselves sitting on the roof of the dorms after a long day. The stars above were bright, and Bakugo leaned back, arms behind his head.

“Y’know…” he started, eyes still fixed on the sky. “I don’t need anyone. But… I’m glad I have you.”

Your heart swelled at the rare softness in his voice. Leaning your head on his shoulder, you smiled.

Even with all his flaws, Bakugo had a heart that beat just for you, and being his high school sweetheart was something no one else could understand.
