His personal history is murky and he has no known vices. Go Eun Ha, known as "Sister Mini" to her web channel's mini audience, is a popular but struggling children's entertainer. She does her best to make children happy with no strings attached. Eun Ha's show is inspired by memories of her childhood companion, Hyeon U. After a series of embarrassing, comical, and painful misunderstandings Ji Hwan and Eun Ha begin to get to know and understand each other. Jang Hyeon U has fulfilled his ambition of becoming a prosecutor but is also a grown-up fan of Sister Mini. He is suspicious of Ji Hwan's past and actions and is uneasy about Eun Ha's relationship with him.
