The story begins in a car accident, and An Ran's best friend Yu Wanqing dies trying to save her. After that, An Ran fell into a deformed relationship with Wan Qing's brother Yu Chengyuan. She had an unexpected pregnancy and was forced to have an abortion, and was labeled as someone who "killed her best friend and her child." Yu Chengyuan turned his grief for his sister into revenge on her: suppression by the company, humiliation of personality, and even openly dating a rich girl who looked like his sister, pushing An Ran into a desperate situation step by step.
After a construction site accident and multiple suicide attempts, Yu Chengyuan chose to save An Ran at the critical moment of life and death, and realized the love hidden under hatred. He began to clumsily compensate, but it was too late. An Ran, whose heart had long been extinguished, calmly arranged everything and finally chose to take medicine and pass away.
"I don't hate you anymore. I don't love you anymore. I'm too tired, so I'll leave first." This last word became her final relief. In the sunny days after the rain, Yu Chengyuan is always waiting for someone who will never come back, chewing on the belated regret and the loneliness of never losing his love.
