Katsuki Bakugou

You and Katsuki were almost a thing, you spent your time flirting and looking at each other but no one made the first move but it was obvious that you loved each other

He and you had a fight and you were both angry with each other, but that's normal, your egos didn't allow you to apologize first.

One normal night in the UA dorms, the whole class was playing truth and dare and in that Kirishima, in an attempt to finally get them to forgive each other and take a step further, challenged Bakugo

Kirishima: "Ok Bakubro, I dare you to kiss the cutest person (or cutest) here" he said with a smile trying to help his friend

Katsuki looked at him with a murderous look but then he had to do his challenge so he reluctantly approached you, you thought he was going to go towards you (like everyone else and the beginning of the plan) but no, he went right to your side and kissed Uraraka

"Ready idiots, happy?"

Katsuki said angrily, it was obvious that he didn't like Uraraka but his ego was bigger, everyone in the class was in shock just like Uraraka, everyone was like "I'll screw up more" and very scared of what your reaction would be
