Since a young age, Eun-jo (
Moon Geun-young) has learned to trust no one and live strong on her own. Used to being dragged from one broken home to another by her manipulative, money-grubbing mother (
Lee Mi-sook), Eun-jo doesn't know what to make of her mother's latest catch Dae-sung (
Kim Kap-soo), the solemn head of a
traditional rice wine brewery. Both Dae-sung and his daughter, bubbly spoiled princess Hyo-sun (
Seo Woo), warmly welcome wary young Eun-jo into their sprawling home, and treat her with a kindness that she simply can't stomach. Instead, she forms a bond with brewery staff Ki-hoon (
Chun Jung-myung), the first person to see past her tough act, and it is his betrayal that will hurt the most. However, Dae-sung's genuine kindness to her eventually melts Eun-jo's defenses, and she learns to trust and love her stepfather. Naive Hyo-sun, meanwhile, stubbornly seeks affection at every turn, only to slowly realize she's losing Ki-hoon and everything else in her life to her cold stepsister. Eight years later, Jung-woo (
Ok Taecyeon) reappears in Eun-jo's life, a boy she used to treat as her little brother who is now a young man determined to win her heart. Reluctant sisters Eun-jo and Hyo-sun both experience angst and rivalry, as their polar-opposite personalities and love-hate relationship bring them through many ups and downs from adolescence to adulthood.
