A befuddled divorcée hires Korea's top male nanny to watch over her two children (both reeling from the divorce) while living in the apartment of her older sister, the self-centered head of a modeling agency.
A difficult client wants Yi-han for his model, forcing Janice to humble herself. Yi-han exacts a price for his compliance; she exacts revenge for his price.
Do-young must carefully reject the unwanted attentions of Janice's business associate, Meng Joo-won, while her daughter and sister enter a reality TV dance contest together.
Both Do-young and Janice deal with insolent underlings who flat out disrespect their authority, and Yi-han, in helping one of them, crosses a line that ends his term as manny.
Since her rescue from the bar fight, Janice's regard for Yi-han changes from kicking him out to ensnaring his interest. Joining in on a family outing would seem the place to do it.
Unable to pay his rent, Oh Shi-hyuk (father of Eun-bi and Jung-min, and Do-young's ex) re-enters his children's lives just as Do-young nervously enters a Project Runway fashion contest.
Do-young becomes distraught at learning Yi-han will be leaving at month's end. In the meantime, Janice moves out, and Jung-min wants to learn baseball.
Janice goes head-to-head against a younger model for the lucrative modeling contract she once rejected. Yi-han and Do-young clash over giving Eun-bi hormonal injections for the onset of puberty.
While Yi-han and Do-young wait for the right time to tell Janice of their relationship, Do-young's ex re-enters their lives, asking for Yi-han's help in getting back together with his ex-wife.
Janice learns the truth of Do-young's and Yi-han's relationship, with nearly fatal consequences. Shin Gi-roo suffers a double comeuppance for her two-timing ways.
A slip-up before Eun-bi reveals that her mother and her manny have been dating, but the fact that no one will confirm it openly stresses her out terribly.
