Xiang Yueqin (played by Wu Xinti), a simple and lovely ordinary girl, has a crush on Jiang Zhishu (played by Li Yuxi), a man of the school. One day, Xiang Yueqin finally plucked up the courage to confess to Jiang Zhishu. However, Jiang Zhishu, who has a very high IQ, simply looked down on Xiang Yueqin, who was careless and reckless on weekdays, and rejected her without hesitation, making Xiang Yueqin the object of ridicule by her classmates. An accident destroyed Xiang Yueqin's home in an instant, and Xiang Yueqin and her father were stranded on the streets with nowhere to go. At this juncture, her father's old friend Chunshuishu reached out to the father and daughter and let them live in his home. However, what Xiang Yueqin did not expect was that Chunshuishu was actually Jiang Zhishu's father. In this way, Xiang Yueqin began to "live together" with Jiang Zhishu by mistake.
