Poor JiYoung....she has to face those difficulties in school and yet busy for her career.....
However, it's a common situation in High school that some students with "undeveloped brain" talk bad things behind you.....even you are 100% well mannered guy/gal.....
I hope JiYoung's friends or classmates or whatever will understand her situation and give her encouragement....
Kamilia will support JiYoung~!
