Li Muchuan and Zheng Xi are each other's exes. After they broke up, they became one of each other's best friends in life. But two people who once loved each other became friends. If they didn't really never love each other, they were too in love to let go. Recalling the past from now, from now to the future, whether our present and past lovers can love again, whether our past lovers can meet again in the future; whether we can still meet love around the corner in the future, and whether we still have the courage to let the future come.

Concept: Life is very long. If our past lovers are still in love, now we have the right to choose. Should we look to the future or embrace our past lovers again?
