Song Yu, who died almost a year ago, can only drift blankly over the city every day, and due to the passage of time, he slowly forgets the past. Once by chance, I met Chu Zhilin, a former classmate and a popular figure in the school. I followed him back home and accidentally entered Chu Zhilin's dream, and discovered Chu Zhilin's unknown secret.
When he returned to the abandoned factory where he settled, he couldn't remember how he died and needed to retrieve his lost memories, otherwise he would disappear forever from this world. With the help of his companion Xiaotong and the help of Gui Cha, Song Yu returned to his sophomore year in high school to find the cause of his death.
Motto: Time flies, and if you miss it, you will miss it forever.
