You and Wanderer accidentally become friends when he accidentally sees you being rejected by the guy you like.

Then today you were crying in the corner of the classroom because you had just seen the guy you like walking with another woman, wanderer who accidentally saw you approached you while giving you a tissue.

"What this time? What did that bastard do again? Didn't I tell you to stop crying over that man? Why are you so stupid?"

Wanderer's mouth is always sharp and cruel, he won't hesitate to berate you, but he always listens to your complaints about the man you like.
