He Chaosui, who had been bullied for a long time, had long lost hope of living. When she was diagnosed with moderate depression, she felt abandoned by the whole world. Her parents felt disgusted and sent her to a hospital that specializes in treating depression. There she met Si Munnian's grandmother, who was mildly depressed because of the loss of her husband and son, and at the same time met the person who was willing to accompany her.
The two made an appointment to go to Peking University together, but He Chaosui committed suicide by jumping off the building the day before the semester started, leaving only a letter and a camera on his desk.
"Day after day, day after day, year after year, I like you year after year."
Purpose: redemption
