Dadzawa and Dadmic! Lets just say that Shinsou, Deku, and Eri don't have the best experiences with 'family'. With Shinsou being left alone after his parents dying in a accident, Izuku's always beating him, and we all know about Eri being tested on.. The timeline is going to be whack. Shinsou was adopted by Aizawa and Hizashi first, then Eri, then Deku.
