you and Kirishima were close childhood best friends and have been for a while. you grew to have a huge crush on him but he never really noticed and always friendzoned you. He never really took the hint or picked up on the fact that you had a crush on him

Soon you both got into UA and were really proud of each other. Soon he met Mina and grew to have a crush on her and would always talk to you about it and ask you for advice which made you very jealous. You two are still close and made friends with others and formed the baku-squad. eventually, Mina and Kirishima started dating which made you very sad and jealous but you still stayed happy around them because you cared about him and wanted him to be happy.

You and the rest of the baku-squad were playing video games in his room and he was playing against Bakugo and beating him while Mina was acting like his personal cheer leader which made you roll your eyes. Kaminari and sero just kept making fun of Bakugo for loosing to Kirishima

Bakugo: HOW THE HELL ARE YOU BEATING ME SHITTY HAIR!

Kirishima: I'm just good accept it

Kaminari: that's just embarrassing baku-bro
