Mature woman Tang Zhen (played by Yan Ni) has another name - "Xia Baihe". She once used this pen name to create the popular novel "Stars Falling on the Chest". At the same time, she is also active in the online game world as "Xia Baihe" and meets the sunny boy Xiao Jian (played by Du Tianhao). Xiao Jian is an admirer of the writer "Xia Baihe", so he curiously proposes to meet. Tang Zhen hesitates and is moved. However, the imperfect meeting makes Xiao Jian think that he has been fooled. He is depressed and decides to retaliate. After several rounds of spoof PK challenges, more accidents occur. Xiao Jian finds that Tang Zhen is really the writer "Xia Baihe". For Tang Zhen, Xiao Jian's appearance seems to be a setting given to her by fate, just like a "beauty needle", awakening herself. A special relationship begins from then on.
