Due to some accidents, Gao Mei-nan (played by Cheng Yu-xi), a trainee nun who originally wanted to become a formal nun, replaced her brother and became a new member of the popular group ANJELL. Gao Mei-nan became Gao Mei-nan. The beautiful girl who was pushed to become an idol was quite uncomfortable at first. Not only did she have to deal with the discerning eyes of a group of fans and hide her identity as a girl, but she also had to deal with all kinds of difficulties and pranks from Huang Tai-jing (played by Wang Dong-cheng), the leader and lead singer of the group. The beautiful girl who had never been in contact with the entertainment industry before naturally caused a lot of jokes and made many things by mistake. In the process of getting along with the members of the group, everyone gradually fell in love with this not-so-tough Gao Mei-nan, and Tai-jing and guitarist Xinyu (played by Huang Rende) developed feelings for the beautiful man beyond friendship. A moving song of growth was played... This film is adapted from the Korean TV series of the same name.
