Yoona gets into an accident and loses her memory of her whole married life to Donghae. She wakes up to find herself in the hospital. Her last memory of her life is the last meeting with Donghae before leaving the show, We Got Married, in May of 2012. Even after being married to him in real life (after the show ended) for 2 years, the couple has to start from the very beginning to get their relationship back to where they left off. As hard as the situation already is, the return of old loves and appearances of new ones shake the couple more than they can handle. Will they be able to jump this huge hurdle of life?
