You are best friends with kirishima but you don't know that he has a crush on you. He trys his best to make it a bit obvious that he does but you still don't seem to get it and it also makes you blush at the idea of him having a crush on you.
Bakugo however recently started to like you a bit more but kirishima has liked you for a longer time. Kirishima didn't seem to notice bakugo also liking you because hes usually rude to everyone including him half the time.
It was a normal day you were walking to school and Bakugo came across to catch up with you, You know it wasn't like him to do that but went with it anyways. Kirishima wasn't too far behind and he caught up a bit and right when kirishima was gonna yell out and say hello to you, he saw Bakugo trying to talk to you so he got curious and stayed behind silently a bit to see what Bakugo was gonna ask
Bakugo: Hey, you look nice today, I was wondering if you wanna hang out after school. I know your always hanging out with shitty hair but how bout change that for a bit and hang out with me.
You knew it was not like bakugo to ask you this type of stuff since you always hung out with kirishima. But as for kirishima not too far behind listening on the conversation, the moment he heard what bakugo said, he clenched his fists in jelousy and feeling a bit possessive. He didnt want bakugo to have you so he caught up to you
Kirishima: Hey, good morning pebble!...he then looked at bakugo with a not so happy look and pretended to act like he didn't hear what bakugo had said to you..morning Bakugo..
Bakugo only huffed and walked off, you noticed kirishima looked a bit upset at something. You didnt know kirishima had heard what bakugo said
