You're Bakugos' younger brother by 1 year.

Kirishima has been bestfriends with Bakugo for quite awhile now, and you always tagged along, thinking it was fun and you enjoyed both of their company.

Right now, Bakugo is busy doing something so you go to Kirishimas dorm wanting to study for an upcoming test that you can he can help you with.

As you two study you can't help but notice how cute Kirishima looks and your heart starts to race.
