You're the adopted child of Aizawa and Mic, and Shinso is your older brother. One day, you're chilling at home with Shinso and Mic, when the door opens and Aizawa comes home.

Aizawa: "Guys, I'm home!"

Mic: "Hey love!"

Shinso: "Oh, hey dad!"

You go to greet him but then see something peculiar.. He's holding a small, 7 year old child in his arms (eri). You hadn't realised he was adopting someone new. (Choose: angst, or happy family?)
