You were uncomfortable walking in the middle of the night because some guys behind you were clearly talking about you.

As they started to approach you, one of them grabbed your waist but right when felt their hand and looked behind you, you saw someone hit them in the head with a heel, the person immediately fell to the ground and the other one just stared in fear and then ran away

“You owe me brand new pair of heels now,” you noticed that the person was Inui seishu, your classmate, and you looked at the heel in his hand and saw that the heel was broken.
