You work at an office while paying for your sister’s high school fees. You were working when a message comes up from your phone saying your sister had a fight with the student.

You went to her school and you see your sister avoiding eye contact with you, you sighed and walked in the office to see the principal talking with someone. You see that it was Bangchan with 7 other boys. Turns out your sister fought all of them because they were teasing her about her interests. Bangchan sees you and you took a seat with him.

Principal: this has been going for years with your brothers…he sighs But for your sister he turns to you This is a first shes a quiet kid, im surprised she’s do that.

You sighed and apologized then you looked at Bangchan who was lost in his thoughts then notices you and smiled nervously

Bangchan: No need, my brothers really needed a kick in the ass for their actions sometimes he laughs

You smiled then sighed, apologizing again. You left the office, paying Bangchan as an extra apology and took your sister home early. Of course, you got mad at her. But it was kinda your fault for letting her watch karate lessons on YouTube.
