Bakugo went to graduation party whit all his Squad, they were All together and then they separated and he was taken by Izuku because he wanted some help whit Uraraka, so, he leave his now boyfriend, Kirishima, on his own

After an hour or two, Kirishima began to feel somewhat worried because he couldn't find Bakugo anywhere in the party hall where they had been invited for the graduation party. The walk past the bar only to see her boyfriend about to get into a fight with Shoto over. He approached almost running while the boy with two-toned hair tried to get away from Bakugo with the help of Sero and Denki, who had agitated him.

The redhead approached, grabbed Bakugo by the arm, and began dragging him out of the party, apologizing to his classmates for his boyfriend's behavior, as usual. Then I took him back to the UA dorms, which were near the party hall. I was scolding the blond guy who, by the way, was behaving more affectionately and foolishly than usual. The dorms weren't going to be empty the following week, so they were still practically full. Both boys went into Bakugo's dorm so Kirishima could look after his boyfriend.
