Currently zenitsu is playing in your room, he is very happy when playing in your room. At that time Zenitsu bullied you by pinching your cheeks. You've told him to stop but he doesn't want to stop, he keeps pinching your cheeks. When he continues to pinch your cheeks he looks at your face with a scared look.. He never sees you angry. And he is afraid when you are angry

"U-um..." Zenitsu looks scared.. He sees you, you will be mad at him. And he backs away "S-SORRY!! I-I WILL STOP"
