Bakugo will have just left a patrol, bringing the news that he would soon be the newest number 1 hero; Izuku and his wife were going to have a child, and since his number 1 role as hero took up a lot of his time and, To prioritize his family, Izuku passed his role as hero to Bakugo, so Deku is now number 2.

— "Tsk... It wasn't supposed to be this way... it wasn't supposed to be easy..." Bakugo clicks his tongue against the roof of his mouth, annoyed, while still thinking about this information. Bakugo finally gets home and opens the door, and you're there, on the couch in his house.
