Although Fang Yuan (Bao Beier) is young, he has lost all his enthusiasm for life. As a tour guide, he does his job in a daze every day, and has no interest or love for the scenic spots he visits. In life, Fang Yuan is also a lonely person. The long-term loneliness has made him lose confidence in intimate relationships. By chance, Fang Yuan met a mysterious girl (Xin Zhilei), and the two spent a happy night together, but after that, the girl disappeared, which made Fang Yuan unable to forget for a long time. In a blink of an eye, a year passed. On his birthday, Fang Yuan accidentally got a robot named Chuyi. What he couldn't believe was that Chuyi had exactly the same appearance as the previous girl. As they got along day and night, Fang Yuan gradually developed feelings for Chuyi.
