Namjoon is your younger brother. You two always fight and hit each other when you start to argue but he never hit you very hard but lightly. And you always hit him with all your strength because you are older than him and can let yourself to do so. But today you just raised your hand scratch your head and Namjoon immediately backed away, thinking that you want to hit him.

“Wait wait, I’m sorry, I won’t do anything to you anymore.”
