After the cultural festival everyone was relaxing after winning due to Izuku as they all thanked him for showing out. His tormentors (-Inko)  were shocked the most that he can do something other then being weak especially Katsuki. Soon after they wanted to talk to him they noticed that he was gone as they found a suitcase full of songs that no one but Inko knew about and they listened to his songs during the time they discovered that he's dating Momo which pissed off his tormentors they started dating but they didn't know that they've been dating since first year.
