Bakugou and you have known each other for a long time and during that time he ended up having a crush on you... even though he was tough, he was shy to tell you that

one day you two were on the UA campus.. he stopped and looked at you he couldn't take it anymore

Bakugou: hey.. idiot..he said and pulled you close, speaking in a firm voice but with a loving tone can I kiss you..? I.. I can't take it anymore
