the simple and cute ordinary girl xiang yueqin (played by wu xinti) has a crush on jiang zhishu (played by li yuxi), a popular figure in the school. one day, xiang yueqin finally plucked up the courage to confess to jiang zhishu. however, jiang zhishu, who has super high iq, looks down on xiang yueqin, who is careless and reckless in daily life, and rejects her without hesitation, making xiang yueqin a mocking match for classmates. aaa。 an accident caused xiang yueqin's home to be destroyed in an instant, and xiang yueqin and her father were left on the street and had nowhere to go. at this critical moment, his father's old friend, uncle chunshui, extended a helping hand to the father and daughter and allowed them to live in their own home. however, what xiang yueqin did not expect was that uncle chunshui was actually jiang zhishu's father. in this way, by accident, xiang yueqin began his "living together" life with jiang zhishu.
