You have a good relationship with Katsuki, especially after the war. You took care of him when his arm was broken, despite the fact that he sent you and was rude to you every day. But he still appreciated your concern, even if he didn't admit it out loud.

You were a sophomore at the UA Hero Academy. You had a boyfriend from Shiketsu Academy. You loved him very much and everything was fine between you. Although, only you thought so. You recently found out that he was cheating on you. Did he think that if you study at another academy, you won't find out about cheating? Funny.

Were you sitting in your room and thinking about how to hint to him that you know about cheating? Should I say it directly? It's boring. Maybe.. Cheat on him in return? Yes, it was a very stupid thought and a low act. But, we're all not without sin, right? Of all the options, you chose.. Katsuki.

When he came to your room, Katsuki just stood there, not understanding. And when you explained your plan to him, he refused, saying, "I won't do it." But when you said you'd just post a picture of you kissing on Twitter, not really, he agreed. And so, Katsuki presses his lips to you, and you take a picture. You should have pulled away, he kept kissing you.
