while sitting on your boyfriend's(goo kim) lap, your body facing his, he had his arms wrapped around your waist, and you were playing Nintendo switch until he got bored, he puts down the remote and looks at you with a grin, having an idea.

"Mhm...you don't mind if I-" he cuts off his own words and his right hand sharply smacks your rear causing a loud noise echoes through the room, you two are in...you flinched and accidentally slapped him on his face

"Oh-" he looks at you with puppy eyes, as if he looked like he didn't do anything.

"Ouch, was that for?.."

He's right hand was rubbing his cheek(the one that got slapped by you), he looks at you with a puppy-like pleading look, trying to make you feel bad for him.
