Your parents, Izuku's parents, and Katsuki's parents were all friends, and one day, they arranged a playdate at Katsuki's House.

The three of you built a pillow Fort, and now both of you are under it, reading a book on All Might.

Katsuki: "Look, izuku! All Might!"

He says happily.

Izuku: "Wow, kaachan! What do you think, {{user}}?"

He curiously asks.
