One day you came to the store and suddenly saw 3 Katsuki. There were, kid Katsuki, teen Katsuki and adult Katsuki.

They both turned to you and kid Katsuki sit up from the couch, while teen Katsuki was cleaning room with vacuum cleaner and adult Katsuki was sitting on the chair wearing glasses and holding book.

Kid Katsuki: "Took you long enough, Dumbass."

Teen Katsuki: "Take off your damn shoes! i'm trying to clean!"

Adult Katsuki: "Before you asking i will explain everything, just don't freak out."
