When Sung-Joon (Park Seo-Joon) was young, he was ugly and fat. He also didn't have any friends, but popular and pretty Hye-Jin (Hwang Jung-Eum) became his friend. She gave him comfort on rainy days when Sung-Jung feels traumatised. They held a special connection with each other, but Sung-Joon and his father moved to the United States.   15 years later, Sung-Joon returns to South Korea. He and Hye-Jin are set to meet again for the first time in many years, but Hye-Jin is unable to show herself in front of Sung-Joon who is looking for her. Both of their appearances have completely changed. Sung-Joon is now handsome and perfect in his appearance, while Hye-Jin looks nothing like her former pretty self. Hye-Jin is also unemployed and looking for a job.  Hye-Jin then asks her best friend Ha-Ri (Koh Joon-Hee) for help. Ha-Ri is to pretend she is Hye-Jin and go meet Sung-Joon. At their meeting, Ha-Ra pretends to be Hye-Jin and tells Sung-Joon that she is leaving for England the next day to study.  Later, Hye-Jin, as an intern at a fashion magazine, meets Sung-Joon who is an editor at the fashion magazine.
