Sheng Xingyang is the daughter of a wealthy family, but her life is overshadowed by her stepmother, Lin Meisu, and stepsister, Sheng Ruoxuan. After her mother's death, Sheng Xingyang was treated as an outcast in her own home. Her younger brother, Bai Cheng, lies in a vegetative state in the hospital, sustained only by the family's medical funds. Sheng Ruoxuan, jealous of her sister's beauty and her own failed attempt to secure a prestigious engagement to Lin Yannan, orchestrates a scheme to ruin Sheng Xingyang. She drugs Sheng Xingyang and leaves her in a hotel room with Fu Siyan, the newly appointed CEO of Dongshen Airlines, intending to destroy her reputation. However, Fu Siyan's aunt, a powerful figure in the Fu family, discovers the incident and covers it up, sending Fu Siyan abroad and ensuring no scandal emerges.
Eleven months later, Sheng Xingyang gives birth to a daughter, Sheng Wanyu, alone in a hospital with no family support. Her father, Sheng Father, threatens to cut off Bai Cheng's medical expenses unless Sheng Xingyang marries quickly to legitimize the child and remove the stigma from the family. Desperate to protect her brother and secure a future for her daughter, Sheng Xingyang agrees to a blind date arranged by Lin Meisu, who intends to introduce her to a low-status man to humiliate her. Unbeknownst to Sheng Xingyang, Fu Siyan, who has harbored a secret crush on her since youth, intercepts the blind date. He poses as the man Lin Meisu arranged, secretly taking the place of the short, unattractive individual Lin Meisu had selected.
Fu Siyan and Sheng Xingyang marry quickly, with Sheng Xingyang believing the union is merely a temporary arrangement to register her child's household. She remains wary of his motives, unaware that Fu Siyan is actually the wealthy and influential CEO she had slept with. Fu Siyan, however, is determined to win her heart and raise her child as his own. He moves into her modest apartment, helps care for Sheng Wanyu, and opens a dessert shop near her workplace, all while concealing his true identity and wealth. Sheng Xingyang, struggling with her career and single motherhood, gradually begins to trust him, though she remains cautious about falling for him again.
Meanwhile, Sheng Ruoxuan prepares for her engagement to Lin Yannan, unaware that her fiancé is actually Fu Siyan's distant nephew. She plans to use the engagement party to publicly shame Sheng Xingyang, forcing her to attend with her husband to display her perceived failure. Lin Meisu and Sheng Ruoxuan plot to expose Sheng Xingyang's "mistake" and ensure she remains subordinate. However, Fu Siyan is already maneuvering behind the scenes, using his power to protect Sheng Xingyang and reclaim the shares her mother left for her. As the engagement party approaches, tensions rise, and Sheng Xingyang begins to uncover the truth about Fu Siyan's identity and his true feelings for her. The story sets the stage for a confrontation where Sheng Xingyang must face her family's cruelty while Fu Siyan prepares to reveal his love and secure their future together.
