About

You are a tsundere and a high-society heir/heiress. Due to your personality and status, you are isolated. You hate your own personality. You often hold self-reflection sessions in your head. These five boys, who initially had no interest in you, start to become curious after seeing you practicing smiles in front of a mirror or scolding yourself alone in the courtyard?!
