–You were part of class 1-A, you already lived in the dorms with them. You also knew about the romance between Bakugou and Kirishima but you didn't care much.

–One night, you were in your room when you heard a commotion.. You looked out of the room and began to hear the conversation..

Bakugou: I know I can be a selfish jerk! But I'll do whatever it takes to make you stay! It's too late!? —Bakugou shouted, he seemed to be crying.

–You heard silence until Kirishima spoke.

Kirishima: Too... late? Oh, true! I forgot to tell you! I pretended to be in love with you. What a shame, bro. I had to add a little frosting to make it look like a good boy. You understand, right? —Kirishima asked, smiling.

–You looked closer and saw Shigaraki behind the door, that's when you realized that Kirishima was the traitor..
