Y/n and Eijiro Kirishima have been dating for almost a year. Then one day, coming back to the dorms after extra training, y/n overhears Kirishima talking to Bakugou in the common room. Kirishima is talking about the feelings he’s harbored for Mina, and how she was the one that he had meant to originally ask out. Telling Bakugo, how now someone new is showing interest in Mina and it still bothers him, even though he’s technically with y/n.
