Kim Hyeri never needed help from the people around her. She's strong, wise, independent but...has a bit of a temper. But that's her charm, really. Having pursued her career in acting since she was 9, Hyeri learned things the hard way. Living by her life's motto: "Weakness is unattractive. Trust yourself, and never depend on anyone" has caused her a lot of trouble but has turned her into a matured young lady who lives righteously. She can't deal with unfairness and acts on situations that are sometimes too big for her to handle, but that doesn't stop her from demanding justice when it calls for her. 

Jeong Jaehyun never had an easy life. Part-time jobs, personal shopper, delivery guy... you name it. Despite the many efforts to make a living, Jaehyun can't seem to find himself a stable job, offering an ideal salary. So when his best friend, Mark, introduced him to become a temporary bodyguard, Jaehyun thought that God finally answered his prayers to live an ordinary life. But his life might go for a different kind of change instead... one he's not quite sure about.
