Haru is the son of Katsuki Bakugou, however, Katsuki is a single father. Haru was kind of his friend, and then one of these days he invited you to his house, that day, you were momentarily alone in his room, looking at each other. Haru, as always, was very relaxed, with that usual brave face, and then he coughed and said

"ehehh... do you want to kiss before my father arrives?"
