Jin-wook and Yoo-mi meet at a Gangwon-do resort and get caught up in a series of misunderstandings and accidents. Yoo-mi is there to attend her mother's second wedding while Jin-wook is there working as a bellhop (a position given to him by his Chairman father to teach him responsibility). Yoo-mi is charmed by Jin-wook's sly and playful personality, and they unexpectedly spend the night together. However, Yoo-mi disappears in the morning, leaving Jin-wook feeling perplexed and insulted.
Three years later, the two meet again when Yoo-mi becomes a nutritionist at the company cafeteria where Jin-wook works. It seems that once a playboy Jin-wook, has given up his carefree life and works at the company owned by his father. He has feelings for Yoo-mi and has kept her bra-pad as a memory of the night that they spent together. At first, he is strict toward her, though it is only because he is looking for reasons to be near her. He later confesses this to her and agrees to wait for her.
During the three years, Yoo-mi's mother has had a second child, Dong-goo, who is now three years old. Upon looking at Dong-goo, Jin-wook's father, the Chairman, mistakes him as Yoo-mi's son, not half-brother. The Chairman tells Jin-wook, admonishing him for having a child out of wedlock with a nutritionist. After finding this out, Jin-wook believes that he has wronged Yoo-mi and warms up to her, seeming to accept Dong-goo as his son. The misunderstanding is eventually cleared up but Yoo-mi gets upset at Jin-wook, accusing him of being with her only because he thought he had a child with her. Then enters a pretty girl, Joo Hye-ri (Jung Da-sol) who is deemed a "suitable" wife for Jin-wook. Yoo-mi's writer friend, Jung Hyun-tae (Kim Jae-young), is shown to have a secret crush on her. With all drama revolving around main characters' mothers, Cha Jin-wook and Lee Yoo-mi finally manage to keep their love strong, while also resolving their personal problems with their parents.
The drama ends with Hye-ri "traveling together" with Hyun-tae and Yoo-mi and Jin-wook attending Yoo-mi's mother's re-wedding and Jin-wook saying "Today is D-day. Do you know how much I've waited for this day?" and Yoo-mi replying "Me too."
