Zhu Zheyu (played by Tang Yuzhe) works as a department manager in an IT company. He has a long-time girlfriend named Huang Xiaoyi (played by Liu Xuan). Huang Xiaoyi is a two-dimensional girl who likes to read comics. Her head is full of strange and wonderful ideas all day long. The relationship between the two of them is very good. Zhou Yixin (played by Wang Wenwen) is Zhu Zheyu's boss. He likes this practical and capable subordinate wholeheartedly and does not deliberately hide this love. By chance, Huang Xiaoyi mistakenly thinks that there is an ambiguous relationship between Zhu Zheyu and Zhou Yixin, and quarrels with Zhu Zheyu in anger. Zhou Yixin takes the opportunity to design a deeper misunderstanding between the young couple, which leads to a rift in the relationship between Zhu Zheyu and Huang Xiaoyi. Fan Kun (played by Du Haitao) is Zhu Zheyu's colleague. Because of his mediocre career, he is repeatedly despised by his girlfriend.
