Chen Yuanting, an unemployed young man, is on his way home from a job interview when he gets into a car accident. When he wakes up, he discovers he has arrived in a parallel world very much like the one he knew as a child. There, he meets Zhong Xiaochun, the girl he once let slip away, his first love. After living there for a while, he realizes that the people around him are strange. They have the same names and appearances as the people in his original timeline, but their lives have taken very different paths. He is terrified. If you were faced with everything you had once lost, would you follow the course of history and let the same regrets happen all over again, or try to change the future...?
