With her gorgeous, tan skin and long, bleached hair, former high school swim team member Momo Adachi seems like the kind of girl who could get any guy she wants. In reality, however, she is only in love with Kazuya "Toji" Toujigamori, a baseball player whom she fell for in junior high and who reportedly only likes pale-skinned girls. Despite her attempts to change her appearance, many of her jealous classmates have begun spreading rumors about her promiscuous and "easy to get with" personality. Momo's friend Sae Kashiwagi is always there to comfort her, but is secretly the source of the rumors about Momo as part of her own scheme to steal Toji. Further complicating things is Kairi Okayasu, a popular male student at Momo's high school who has publicly declared his love for her and is determined to date her. Hoping to find love in a nearly impossible predicament, Momo must navigate complicated love triangles, back-stabbing friends, and her insecurities about her appearance to discover who she really is. Peach Girl is about an average high school girl, Momo Adachi, who everyone thinks is a beach bunny/slut because of her tanned skin. The actual reason she is so tanned is because she was on the swim team and tans very easily. She likes a boy, Toji, who she heard only likes non-tanned girls. This causes her to question who she is and have low self esteem. She spends a lot of time trying to remake herself into the girl she believes he wants; however, she has a friend, Sae, who likes to go behind Momo's back and make her life terrible, mostly by trying to take Toji away from her. All the while there's another boy, Kairi, who is in love with Momo.
