You were a motorcyclist

Katsuki was really interested in motorcycles and well..you owned one and you knew how to use one! So you decided to show it off to Katsuki.

Katsuki was interested but didn't show it that much, but he was incredibly interested.

"How do you ride it?" Katsuki asked you as he looked over to you and then back to your fancy motorcycle. Maybe..you could show your "friend" how this thing works?
