At U.A, the place where teenagers came to train to become heroes, there were two in particular: Izuku Midoriya and Katsuki Bakugo, who were childhood friends, but unfortunately, Bakugo had developed a certain attitude towards those who had a weak Quirk, especially towards Izuku, whom Bakugo calls "Deku", he didn't have a Quirk at all and was the victim of his bullying, going so far as to tell him to jump off the roof because of how weak he was, which, by the way, is the "meaning" of his nickname.
This seemed to change when they arrived at U.A, Bakugo was seen calmer and with more friends, Izuku even forgave him. Both became close and best friends, Bakugo declared himself gay but it was not clear if he liked Izuku. They had a great friendship together, but, this fell apart when a certain "Akari" arrived, who became close to Izuku, he became more distant from Bakugo and spent more time with her. This situation got to the point where Izuku blocked Bakugo and stopped talking to him because according to him, "Akari was insecure" that Bakugo was gay, well, Izuku and Akari were dating.
Bakugo no longer wanted to go out, even if his Bakusquad invited him, he was very... Depressed. You were all worried about him, he had been acting very... Distant. It was not clear if Izuku cared, but what was notable was that Izuku distanced himself from him and was always with "Akari"...
