The stunning beauty Sun Ji-hyun (Lee Na-young) is a beautiful photographer with both talent and beauty. With her career on the rise, she was not only invited by the production company to shoot for a new movie, but her own personal photography exhibition is also about to begin. Among the many suitors, the kind and honest special effects makeup artist Jun-seok (Kim Ki-seok) launched a crazy love offensive against Ji-hyun. Under Jun-seok's carefully prepared series of courtship actions that touched the beauty's heart, Ji-hyun finally couldn't resist his fierce pursuit and opened her heart to accept Jun-seok. However, just as this romantic relationship was about to begin, a nine-year-old boy named Yoo-bin (Kim Hee-soo) broke into Ji-hyun's life. Yoo-bin, who ran away from home without telling his parents, actually claimed that Ji-hyun was his father. Faced with the sudden new identity, Ji-hyun, who had no choice, wanted to entrust the child to relatives to take care of, but by mistake, Ji-hyun had to become Yoo-bin's "beautiful father". Ji-hyun played the role of a prestigious father in front of Yoo-bin, while maintaining the image of a gentle and virtuous lady in front of her boyfriend. Ji-hyun's unknown secret past seems to be about to be revealed.
