Xu Zhiqiao, an eighteen-year-old girl from out of town, moves into the Ji family in Shencheng after her mother marries Ji Huailuo's father. She has just finished the Gaokao and will begin college soon. Ji Huailuo, her newly acquired stepbrother, resents her presence. To get transferred from the logistics department to a core department, he reluctantly agrees to his father's order to bring Xu Zhiqiao to his birthday party at the Chengnan private club. Xu Zhiqiao also has her own goal: if she obediently attends the party without causing trouble, her mother will allow her to live in the dormitory when school starts, giving her escape from Ji Huailuo's hostility.At the club, Ji Huailuo warns her not to smile at his friends, especially Zhou Cong, the crown prince of the Zhou family, who is a notorious playboy with a sinister personality. Inside the private room, Ji Huailuo's friends have arranged a surprise with a woman lying on a table full of flowers. Ji Huailuo immediately covers Xu Zhiqiao's view and orders it cleaned up, knowing Zhou Cong hates such scenes. A friend named Jiang Bin makes sarcastic remarks, insinuating that Ji Huailuo is only favored by Zhou Cong because of his stepsister. Before Ji Huailuo can fight, Zhou Cong arrives, holding a suit jacket in one hand and loosening his tie. He forces Jiang Bin to repeat his words, then threatens him with the tie. The tension subsides when Ji Huailuo mediates, claiming he has a chatterbox to deal with. Zhou Cong then offers to accompany Xu Zhiqiao for a walk, and Ji Huailuo agrees.Outside the club, Xu Zhiqiao receives a call from her mother, Xu Shu, who encourages her to get along with her stepbrother. Xu Zhiqiao lies that she had fun and made new friends. Zhou Cong overhears and mocks her liar skills. He tells her his full name is a lyric from "Bu Suanzi," and when he bluntly asks if she has ever been in a relationship and proposes dating, she refuses, stating that "one radish, one hole" and he is definitely not her hole. She runs away, calling him "brother," and escapes back inside. His friends observe his defeat for the first time, commenting that he is being beastly, as she is just starting university while he has already graduated.Later, Xu Zhiqiao wanders alone by the moat, unable to go home because Ji Huailuo's party will last all night. Zhou Cong pulls up beside her in a black Cullinan, showing her an ongoing call with Ji Huailuo, who orders her to go home. She reluctantly gets into the passenger seat. During the ride, Ji Huailuo angrily scolds her through the speakerphone, and she bursts out saying she would rather have a father like Brother Zhou Cong. After hanging up, Zhou Cong teases her about not wanting a boyfriend but wanting a father. She replies in frustration that she meant she wanted to use a bad example to highlight a worse one, making him laugh.At the Ji villa, housekeeper Li Jie tells Xu Zhiqiao that Zhou Cong is a neat freak—no one dares to sit in his car for fear of leaving a hair. Xu Zhiqiao recalls that she not only rode in his car but also kicked his car door in revenge, leaving a grey-white shoe print. She learns that Zhou Cong was raised by his grandfather, a veteran who trained him to be decisive, efficient, and quick to set goals, even allowing him to make huge mistakes like nearly toppling the Zhou Corporation once. This made his personality rigorous and meticulous. That night, Xu Zhiqiao receives a WeChat friend request from Zhou Cong (profile picture: a headset, name: ZC) but ignores it.The next morning, Ji Huailuo returns drunk, smelling of alcohol. He tells Xu Zhiqiao he wants to get a dog, implying she should not mind because she will be going to school soon. When she hesitantly calls "Bro..." he stops and waits. She corrects herself to "Brother" and tells him to go upstairs to sleep. As he turns, he mentions, "That... this is your Brother Zhou Cong's phone number. Add him, otherwise he will come to visit today." Xu Zhiqiao now faces the dilemma of either adding the arrogant heir who proposed dating her or facing the consequences of his visit.
The story follows Xu Zhiqiao's navigation of a forced family dynamic, her resistance to being used as a tool, and the unexpected and bold pursuit by Zhou Cong, whose decisiveness and high status contrast sharply with her ordinary life. Her underlying desire to move into the dormitory and gain independence remains her driving force. The tension between her, her hostile stepbrother, and the overbearing yet compelling Zhou Cong sets the stage for a fraught relationship full of conflict and attraction.
