Shen Xiuzhi had been sponsoring the orphan Yu Qingyuan for many years, but after marriage, he became celibate and cold. Yu Qingyuan, celebrating a project's success by offering him an aphrodisiac, failed. She then unexpectedly discovered hundreds of photos of her stepsister, Shen Wanrou, on her husband's computer, realizing she was a stand-in. During a bar fight, Shen Xiuzhi fought to protect Shen Wanrou, and Yu Qingyuan was retaliated against, suffering a concussion. Shen Xiuzhi, however, took Shen Wanrou to the hospital. Shen Wanrou spread rumors that Yu Qingyuan had used "special means" to secure the project, leading Shen Xiuzhi to slap her and dismiss her from her job.
When Yu Qingyuan repaid her sponsorship, she and Shen Wanrou were kidnapped simultaneously. The kidnappers forced Shen Xiuzhi to choose between them, and he unhesitatingly chose Shen Wanrou. Desperate, Yu Qingyuan jumped from the moving vehicle and was seriously injured. While in the hospital, she proposed a divorce, only to be humiliated by Shen Xiuzhi with the excuse of "compensating for their physical relationship." Yu Qingyuan then tricked Shen Wanrou into signing the divorce agreement with her private seal, leaving her with jewelry and nothing else. After Yu Qingyuan left, Shen Xiuzhi realized Shen Wanrou's true colors and regretted pursuing her. Meanwhile, Yu Qingyuan had arrived in Yuncheng and, drunk at a bar, "bought" Xie Chengyan for a night for 20,000 yuan, only to discover he was the youngest son of the powerful Xie family from the south, whom she had met briefly at a charity event in her youth. Xie Chengyan confessed his long-standing crush, and the two fell in love. Their best friend, Song Yan, discovered their relationship, and Xie Chengyan used his tea and coffee resources to support Yu Qingyuan's business venture.
Shen Xiuzhi drove Shen Wanrou away and forced her into a marriage alliance, ordering his special assistant, Zhou Lin, to restore Yu Qingyuan's belongings. He then pursued her to Yuncheng. A guesthouse owner witnesses Xie Chengyan and Yu Qingyuan passionately kissing, leading to a confrontation with Xie Chengyan. Yu Qingyuan publicly accuses Shen Xiuzhi, who, unwilling to accept this, forcibly kisses her and is slapped. Torn between Shen Xiuzhi's remorse and desperate attempts to win her back, and Xie Chengyan's passionate yet rational love, Yu Qingyuan chooses a sober approach to life, but doesn't shut her heart off, instead accepting Xie Chengyan openly. Ultimately, she and Xie Chengyan achieve a happy ending.
Shen Xiuzhi and Shen Wanrou finally face their comeuppance. Shen Xiuzhi is filled with remorse; the cage that imprisoned her has become his own prison.
