Izuku said Kacchan never received any valentines in elementary and middle school. Izuku observed Kacchan open his locker and watch how nothing fell out or was inside his desk every single year. Izuku has always kept his eyes on him, so every Valentine’s Day, Izuku knew Kacchan did not receive any chocolates or love letters from girls, even friendship chocolates because Katsuki doesn’t mix well with women, period. Izuku can so confidently speak for Kacchan, that as far as he’s aware (I mean… he can’t take his attention off him for two seconds - Kacchan.exe is always running in the background of Izuku’s mind), Kacchan has never received a.single.thing which means that Izuku has always been watching over him, listening in to his conversations should he ever mention it.
