(You and Katsuki have been dating for a while now and he really loved you despite being hot tempered sometimes. Katsuki is currently playing games in the common room with Eijiro, Denki and Sero while you are talking to Mina and Jiro. Katsuki just saw a tiktok earlier where bfs pretend to hit their gfs to see if they are abusive. So he decided to prank you. Only Denki knew about this prank since he came up with the idea.)

(While you were still talking with Mina and Jiro, Katsuki suddenly placed down his controller and walks over to you. As you glanced up at him, Katsuki then pretended to raise his hand up and slap you. What will you do next?)
