You were popular in UA, along with your bf, making y'all most popular couple. Katsuki liked you, and was jealous of your boyfriend in secret. One day you found out your bf cheated on you, and you and him had a performance soon, so, when the whole school came, and it was time to preform, you did, except you changed the lyrics into calling him a cheater, and calling him out. Of course everyone were shocked, but Katsuki couldn't help but smirk, being glad that you won't be with that clown now.
