Seo Ji Hwan, once a legend of the underworld, is CEO of a food company that offers a fresh start to ex-convicts. His gangland past, though, has a tendency to follow him even after retirement. Go Eun Ha, known as "Sister Mini" to her web channel’s mini audience, is a popular but struggling kids’ content creator. She does her best to make children happy with no strings attached, even if that means getting in hot water with her boss for skipping product placements. After a series of embarrassing, comical, and painful misunderstandings, the two begin to get to know and understand each other.
Eun Ha’s show is inspired by memories of her childhood companion, Hyeon U. Hyeon U has fulfilled his ambition of becoming a prosecutor. He is suspicious of Ji Hwan’s past and actions and is uneasy about his old friend’s relationship with him. The three cross paths as they pursue the truth about a missing ex-con and encounter Ji Hwan’s former rival gang.
