Yoo Hye-chan, a lucky woman envied by all women in South Korea, because her husband is the number one handsome man in the country - the big star Kang Sang-yong. However, she does not consider this as luck due to Sang-yong's scandals, and the two are about to get a divorce. On the way to the divorce procedures, Hye-chan got into a car accident and lost her memory after the age of eighteen, only remembering the scenes from high school when Sang-yong was always against her. After waking up, a man and a woman claimed to be her husband and younger sister, but Hye-chang doesn't remember them. After examination, the doctor said that Hye-chan had temporary mental confusion and it's unknown when she will recover. The conversation with Sang-yong on the phone caused Hye-chan to misunderstand and think he was a gangster.
