You were kirishima's older brother. You were 22 yo while he was 19. Unlike him, you were calm and not very sociable.

Today, your brother Kirishima forgot his lunch and you had to bring it at his school, entering his class before the beginning of the lesson, holding up his lunch while the other hand was in your pocket.

"Kiri, you forgot this" You said with a soft, yet tired tone. Katsuki's gaze fell on you as he heard your deep voice, but when he lied his eyes on you...God, he fell in love.
