Ever the strong and decisive career woman, Tae Hee (Kim Nam Joo) falls in love and marries Jong Soo (Jung Jun Ho), even though he's a bit of a loser.

Misunderstandings grow over time between Tae Hee and Jong Soo, putting their marriage into danger. Meanwhile, Tae Hee's apathetic chaebol boss Yong Shik (Park Si Hoo) grows more serious about his work with her guidance - and ends up falling hopelessly in love with her.
