Song Fuxue, the third miss of the wealthy Song family on Hong Kong Island, is abruptly expelled from her home after the family patriarch discovers she is a fake heiress—switched at birth with her sister Song Ni. Stripped of her identity, frozen accounts, and separated from her parents and sister who are overseas, Song Fuxue attempts to flee to Beijing to seek refuge with her cousin He Yichen, who has always doted on her. En route to the airport, she is kidnapped by gangsters involved in Hong Kong’s violent turf wars. During the abduction, she escapes by jumping into the sea, surviving the ordeal but losing her phone, money, and consciousness after being struck by a car on a remote mountain road.
She is rescued by Pei Shangyue, a powerful and cold-hearted CEO of the Pei Corporation in Beijing. Suffering from head trauma and amnesia, Song Fuxue wakes up in Pei Shangyue’s private estate on Hong Kong Island. In her confused state, she mistakes Pei Shangyue for her older brother—a man she vividly remembers despite having no other memories. Her clingy, affectionate, and innocent demeanor disarms Pei Shangyue, who, against his usual cold nature, agrees to let her believe he is her brother. The doctors attribute her misidentification to trauma-induced confusion and suggest her memory may return naturally.
Pei Shangyue brings Song Fuxue back to Beijing, where she settles into his residence, Yunqi Residence. She is lively, chatty, and completely dependent on him, referring to him constantly as “Older Brother.” Her amnesia leaves her unaware of her true identity, though she occasionally experiences nightmares about being chased and jumping into the sea. Meanwhile, in Hong Kong, her biological family—the Song family—and her cousin He Yichen are desperately searching for her. The Song family patriarch had concealed her disappearance to seize family assets, but her mother and sister, along with He Yichen, are determined to find her and restore justice.
As Song Fuxue adapts to life in Beijing, she and Pei Shangyue grow closer. She brings warmth and vitality into his previously sterile and lonely life, and he finds himself increasingly protective and attached to her. He buys her a kitten named Cake, takes her sightseeing, and cooks for her, all while maintaining the facade that he is her brother. However, underlying tensions emerge: Pei Shangyue struggles with his growing romantic feelings for her, knowing that her memory may one day return and she will discover the truth. Song Fuxue, meanwhile, remains blissfully unaware, trusting him completely and expressing her desire to stay by his side forever.
The story sets up a central conflict between Song Fuxue’s true identity and her fabricated bond with Pei Shangyue. As He Yichen and the Song family close in on clues about her whereabouts, and as Song Fuxue’s memories begin to flicker back through dreams, the fragile illusion Pei Shangyue has constructed faces the threat of collapse. The narrative explores themes of identity, belonging, and the ethical boundaries of deception, as both characters navigate a relationship built on a lie that neither is willing to abandon.
