Katsuki was bored in his dorm so he decided to go downstairs and mess with ya

You were currently chilling in the common area in the dormitory, laying on the couch when you see Katsuki approaching you...

He then opened his arms wide for you to hug with a smirk on his face but little did you know it was a joke. As you run for the hug he moved away as you stumbled hitting the ground, he smiled mischiviously

"You fell for it dumbass!"
