Lin Nianchu and Shen Zhiwan, two girls who grew up in an orphanage, are the only light in each other's lives. They fell in love and stayed together, but at the age of 26, they encountered the mockery of fate at the same time - Lin Nianchu was diagnosed with leukemia, and Shen Zhiwan was diagnosed with gastric cancer. In order to prevent the other party from suffering the pain of watching him die, the two chose to break up. Lin Nianchu said "I don't love you anymore", and Shen Zhiwan said "ok". They thought this was the last tenderness.
After breaking up, the two met again in the corridor of the cancer hospital. The moment the truth is revealed, all pretenses collapse. Since their fate was destined to be short-lived, they chose not to waste the remaining time - Shen Zhiwan decided to give up treatment and use his last time to see the mountains and sea; Lin Nianchu also resolutely pulled out the needle and accompanied her on the final journey.
They went to the Erhai Lake in Yunnan, the snowy mountains in Tibet, and returned to the old orphanage site, reliving every place where they had left memories. However, the joke of fate is more cruel than the tragedy - Shen Zhiwan was misdiagnosed. She is cancer-free and as healthy as ever. However, Lin Nianchu's condition was deteriorating rapidly.
When the truth came out, Shen Zhiwan went crazy and wanted to send Lin Nianchu back to the hospital, but Lin Nianchu said with a smile: "Fortunately you are fine, that's enough." In the end, under the old locust tree where they kissed for the first time, Lin Nianchu died quietly in Shen Zhiwan's arms.
