The story tells the story of Xu Chi, an autistic male protagonist, who travels through time and space and returns to high school to meet Lin Momo, a girl he met in college. Lin Momo has always liked a boy named Xu Chi since college. She had so many opportunities in college, but she passed him by time and time again because of her inferiority complex and timidity. And these opportunities were carefully created by Xu Chi. He watched her study hard, work hard to make money, and live an active life, but as soon as he got close to her, she hid herself and didn't reply to her letters of love.
After both time travel, Lin Momo changed her past personality and was sure that she would meet Xu Chi in college. She struggled repeatedly in her heart, but she still couldn't resist Xu Chi's efforts to distract the crowd from favoring her. Xu Chi began to test Yuan Qian's intentions, implicitly and blatantly declaring his ownership of her to everyone. This time, she wanted to study hard, so he accompanied her; she wanted to start a business, and he was with her; she couldn't reconcile with her family of origin, so he tried his best to love her and warm her, and finally they were together.
