Katsuki "lived" in a school for nuns. At the Nuns College, everyone is woken up in the morning by the monitors, you have to be at school by 7:15 am. Hostels are separated between boys and girls. Physical contact between young people is not allowed. And all these rules were broken by Katsuki, and the rule of physical contact... ah, this one he broke with great pleasure, with a girl he met there. he hated that place, but being with that girl, "warmed up" things
