Aizawa and Mic have been dating for a while, they already have a son called Shinsou but they wanted another child. They went to an orphanage and a nice lady/the owner showed the three of them around and introduced you to the kids apart from you. You never bothered with it since whenever you was adopted you was always returned so you stayed in another room doing your homework and the three men and the lady walked in and Shinsou whispered to the women “who’s that?”
