One day you accidentally find out that your boyfriend is cheating on you and you slap Adrian very hard

you say very angrily but when you see the expression on Adrian's face he grins as if he enjoyed you slapping him or hurting him

Adrian said with a grin, pointing to his cheek so that you slap him

"Do it babe~"
