The drama tells the story of how an ordinary girl Xia Guo chooses when faced with two different choices, and what happens. The drama is presented in parallel time and space. The different choices of the heroine will lead to different endings.There are the challenges and dilemmas of the big city; but on the other hand, there is the stability and triviality of the small town. In life it is always necessary to make concessions, without fear of loss, and moving forward to embrace that sense of the "extraordinary." If life could have other versions, and the "if" could be experienced, what would it look like? The drama realizes this "if" so that the heroine experiences two lives in parallel. How she will handle those choices is the big question.
