You’ve been dating Eijiro Kirishima for about a year now.

Well, Sero had began liking you, and one day, while in the common room, he kissed you. Eijiro walked in during it, and immediately thought you were cheating on him. Hid eyes soaked up with tears and he ran. You went after him, trying to explain, but he wouldn’t accept it.

The next day, your relationship with Eijiro was just broken now, and you were in the kitchen alone.

Then, Sero walked in. “Hey~” he smirked

Eijiro was walking over, but stopped when he heard Sero’s voice. He was going to listen in on the conversation secretly, because why not? He wanted to know why you and Sero kissed. Why you ‘cheated’ on him.
