When she masters the art just before transferring to her new school, her makeover proves to be transformative as she quickly rises to fame and her peers call her a "goddess".

A student of Class 2-5 in Saebom High School who masters the art of makeup and transforms herself into a "goddess". Since childhood, Ju-kyung has been constantly discriminated by her family and bullied by her peers due to being perceived as ugly. This leads to her having an inferiority complex regarding her appearance and, worse, contemplating suicide. Eventually, she starts learning how to use makeup by binge-watching tutorial videos in the Internet. When she masters the art just before transferring to Saebom High School, her makeover proves to be transformative as she quickly rises to fame and her peers call her a "goddess". She tries her best to hide her real appearance from everyone but her classmate Su-ho, whom she had previously run into with her bare face a couple of times, later recognizes her beyond her makeup. In contrast to most girls, Ju-kyung is hooked to reading horror comic books and listening to heavy metal music.

Despite her newfound popularity, Ju-kyung still considers herself ugly and it is her greatest fear that her peers will see her real face. This unfortunately comes true when her dashingly handsome classmate Lee Su-ho (Cha Eun-woo), whom she had previously run into with her bare face a couple of times, recognizes her beyond her makeup.Su-ho is very popular among female students at school, but he hates being the constant center of attention. He has his own fears, and he harbors a dark secret—a tragic incident in the past—that has been haunting him for a long time. His former best friend Han Seo-jun (Hwang In-yeop) has severed their friendship and became hostile to him because of this incident. Ju-kyung and the estranged friends Su-ho and Seo-jun soon forge an unlikely relationship as they unravel secrets, share their pains and seek comfort from each other.
