In the busy city of Seoul, three generations of witches have been living without anyone noticing. Maeng Ye Soon and Jo Aeng Doo, two other witches, work with Kang Cho Hong to run a restaurant. They try to keep a low profile, but Cho Hong's good looks make Hwang Jae Wook, a guy from the neighborhood, try to get close to her all the time. When Ma Sung Tae, the landlord of the building where Cho Hong and her friends live, shows up one day, their quiet lives are turned upside down. Sung Tae wants to face a traumatic event from his childhood that happened in that building. Since Sung Tae is always looking into their business, can Cho Hong keep her true identity from him?
