Lin Xiaoman, a twenty-six-year-old ordinary office worker, lives a peaceful life, but deep down in his heart there is always an obsession about "what if" - about Bai Yueguang Jiang Yi who left without saying goodbye ten years ago, and about his current boss Chen Yu who is gentle, restrained and aloof.
An unexpected reunion on a rainy night sent Jiang Yi back to her world. The once brilliant young man's eyes were now filled with vicissitudes of life and unfinished words. At the same time, Chen Yu's quiet care and exploration also penetrated her lonely daily life like a warm current. On one side is an unforgettable old dream, with unsolved mysteries and youthful regrets; on the other side is clearly visible tenderness, representing a future that is stable but requires courage.
In contrast to the fact that her best friend Xia Xiaotang and her childhood friend Zhou Mingxuan's "happy enemies" finally got married, Lin Xiaoman was forced to examine his own heart. She opened the notebook that had been dusted for ten years and discovered Jiang Yi's secret confession; she finally saw clearly the sincerity and helplessness behind Chen Yu's restraint. However, as time passes, every hesitation and miss is like the butterfly effect, letting the possibility of "what if" pass quietly at the fingertips.
This is not a simple multiple-choice question about love, but a journey of reconciliation about self-growth. Lin Xiaoman finally understood that indulging in "what if" assumptions would only create new regrets. Regrets in youth are marks engraved on the rings of the year. They cannot be erased, but they do not have to become a shackles for moving forward.
Intention: Don't miss the cherished moments again, don't leave new "ifs" because of cowardice.
