Pei Yan is a talented jewelry designer and the second daughter of the wealthy Pei family in Sui River. She has been in a three-year relationship with Li Yueting, the heir to Blue Sail Entertainment, and they are one month away from their arranged marriage alliance. Despite her deep affection, Pei Yan has endured neglect, as Li Yueting frequently parties in nightclubs and maintains emotional distance, never even kissing her. Her skeptical older sister, Pei Ying, warns her repeatedly about the mismatch, but Pei Yan remains hopeful that Li Yueting will settle down after marriage.
The story begins on a night when Pei Yan, suffering from a foot injury, calls Li Yueting from her studio while he is at a nightclub with his influential friend, Fu Huaizhou. Li Yueting dismisses her demands for pickup, telling her to take a taxi home. Devastated, Pei Yan receives a photo from Li Yueting showing him arm-in-arm with another woman. Simultaneously, Fu Huaizhou, who has harbored secret feelings for Pei Yan since he was twenty, observes the interaction from the nightclub. After Pei Yan leaves, Fu Huaizhou tracks her down and offers her a ride home. During the drive, Pei Yan confronts him about the woman in the photo, but Fu Huaizhou deflects, claiming ignorance. He drops her off at her family estate, asking if she hates him, to which she replies that she dislikes him before leaving.
The next morning, Pei Yan receives a leaked video of Li Yueting drunk, confessing his love for another woman named Ning Ran and dismissing his engagement to Pei Yan as merely a family arrangement. Confronted with this betrayal, Pei Yan decides to end the relationship. When Li Yueting returns home expecting her to make him hangover soup, she instead serves him the news of their breakup. She returns the butterfly brooch she designed for him, symbolizing her desire to break free, and throws it away. The video leak triggers a media storm, with headlines exposing Li Yueting’s disdain for his fiancée. Fu Huaizhou orchestrates the leak to protect Pei Yan and dismantle the engagement, while also leaking scandals about the Li family to weaken their position.
Li Yueting, panicked by the public fallout and his father’s anger, realizes he cannot afford to lose the Pei family alliance. He attempts to reconcile with Pei Yan, but she remains resolute. Fu Huaizhou takes Pei Yan to a private amusement park to distract her, where their physical proximity intensifies the tension. Li Yueting’s sister, Li Jialin, witnesses them together and mistakenly believes Fu Huaizhou is stealing her brother’s partner. Li Yueting confronts the couple, leading to a heated argument where Pei Yan asserts her independence. Fu Huaizhou intervenes, driving Pei Yan away while Li Yueting trails behind.
Later, Pei Yan goes to a nightclub with her friend Xia Tingwan to drink away her sorrows. Fu Huaizhou follows her after receiving a photo from his friend Gu Jingyi. In the club, Pei Yan is harassed by Li Yueting’s associates, but she stands up for herself, announcing their breakup and warning them to stay away. Fu Huaizhou escorts her to a VIP room, where a drunk Pei Yan mistakes him for a male escort and asks him to kiss her. As Li Yueting bursts into the room, Fu Huaizhou kisses Pei Yan passionately to provoke jealousy and assert his claim. Pei Yan, still intoxicated, clings to Fu Huaizhou and refuses to leave with Li Yueting, slapping her ex-fiancé when he tries to take her. The story concludes with Fu Huaizhou carrying Pei Yan to his car, whispering that the "big bad wolf" is there, as Li Yueting watches helplessly, realizing he may have lost her forever.
