Eun Jo (Moon Geun Young), who lives with her mother since years ago (and also her mother's lover), finally gets a new family home when her mother remarries to a kind man who owns a winery. At first, she denied it, and even attempted to escape rather than dealing with the attempt of being schooled. The cynical Eun-Jo is unable to accept the affection of her new step-sister Hyo Sun (Seo Woo) and step father Dae Sung (Kim Gab Soo). Hyo Sun with her bright character is the apple in her father's eyes and Eun Jo's mother goes out of her way to fulfill the role of Hyo Sun's mother, causing her to neglect and act harshly towards Eun Jo. However, Eun Jo finds a friend in Ki Hoon (Chun Jung Myung), a college student working at the winery who becomes her own prince. Ki Hoon eventually leaves to take care of personal issues, but Hyo Sun's jealousy of Eun Jo causes her to make Eun Jo believe that he has abandoned her. The three reunite 8 years later to begin the main plot - a modern adaptation of Cinderella with a twist. Jung Woo (Taecyeon), a boy that Eun Jo considered her little brother 8 years ago, appears in order to be near her and fulfills the role of a "fairy godmother" to her. A love triangle forms when Hyo Sun falls for Ki Hoon, who is still in love with Eun Jo. The feeling of betrayal lasts with Eun Jo, creating misunderstandings and difficulties. However, the kindness of Eun Jo's stepfather (Hyo Sun's father) begins to change everyone's lives, making this a tale of growth and redemption.
