Season 1

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.

At Yi-han's urging, model Jun-ki brings Janice up on assault and sexual harassment charges.

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.

For love or money - Janice must decide between the two when she's presented a lucrative contract with a steep stipulation clause.

In exchange for an interview, Yi-han induces a TV producer to feign being his ex-girlfriend in order to get Janice to withdraw her offer of love.

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.

While Janice, as a "wronged woman," helps Jun-ki become a sexier model to teach Gi-roo a lesson, Yi-han teaches Jung-min piano to attract a classmate.

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.

Eun-bi runs away, taking Jung-min with her, and threatens not to return till Manny moves out.
