unfaithful bakudeku

Bakugou has been Deku's partner since the beginning of UA Academy, always being clingy and teasing each other, but... One day, when a girl enrolled at UA, Bakugou became more distant and colder, not wanting to talk to you. The girl's name is Kaede, a cook who clearly loves to cook. She works in the kitchen and is the leader, and she used to be the former leader of the science club. Bakugou barely spoke to you again until he was looking for Kaede, and a few hours later, during free period, Ochaco tells you that she saw Bakugou kissing Kaede in the empty classroom of C-B2, and you just stood there, frozen with a dark expression.
The story continues! What will you do after that?! Bakugou cheating on you?
