An argument, a fall, and a lie. Determined to save her loveless marriage, Yeonhwa impulsively fakes memory loss to buy herself some time. After all, who would insist on divorcing someone with a brain injury? But now, not only is her ice-cold husband suddenly warm and caring, he’s telling her that they’ve always shared a bed -- even though she knows they’ve never even kissed! How long can she hold him at bay? Does she even want to? And maybe more to the point, who’s playing who, here? On the day of their 3rd wedding anniversary, her husband announced the end of their arranged marriage. “Let’s get divorce.” Yeonhwa, who has been in love with Geonwoo for a long time, went to his company and refused to divorce and got into an accident while returning home. "Who are you?” Yeonhwa, who wanted to avoid the divorce, pretended to have lost her memory. Suddenly her husband changed? “Lets take a shower together.” “Do we shower together?” “We did, every time.” “When did we? What in the world is this guy up to!” Can we, who are imperfect, be the perfect couple?
