My husband lost his memory after three years of marriage.

Ji Linglu is the cherished only daughter of a wealthy real estate tycoon, raised in luxury and protected from the harshness of the business world. She marries Gu Yu, the cold and powerful heir to the Gu Group, in a union that surprises the upper-class circle due to her seemingly ordinary background, though her family's immense wealth and influence remain hidden from public view. Their three-year marriage is characterized by Gu Yu's intense, almost possessive devotion. He strictly monitors her movements, enforcing a curfew and forbidding her from frequenting bars, driven by a deep-seated fear of losing her. Despite his controlling nature, their relationship is affectionate, with Gu Yu frequently expressing his love and doting on Ji Linglu and their young son, Gu Mo.

The narrative tension escalates when Ji Linglu secretly attends her best friend Bian Yue's birthday party at a bar, lying to her husband about her whereabouts to avoid his disapproval. She returns home past midnight, believing she has successfully concealed her actions, only to find Gu Yu waiting for her. He had cut short a business trip to surprise her. The confrontation is tense, with Gu Yu displaying rare anger, but Ji Linglu's affectionate appeasement and apology eventually soften him. He reiterates his fear of losing her, revealing that his strictness stems from a traumatic incident a year prior when she got drunk and he could not reach her. The couple reconciles, and the following morning is filled with tender gestures, including a ruby bracelet gift and whispered declarations of love, reinforcing the stability of their seemingly perfect life.

However, this stability is shattered by a catastrophic event. Gu Yu, while driving home from work after buying treats for his wife, is involved in a severe multi-vehicle pileup caused by an out-of-control truck. He suffers critical head injuries and falls into a coma. Ji Linglu, who had been preparing dinner and opening a bottle of wine, receives news of the accident and rushes to the hospital. The family is thrown into turmoil as Gu Yu undergoes emergency surgery. Fortunately, the surgery is successful, but Gu Yu remains unconscious for several days. During this time, Ji Linglu stays by his side, her fear and love evident, while the Gu family and her own family provide support and manage the business crises resulting from his absence.

When Gu Yu finally wakes up, a devastating complication emerges. He has selective amnesia, specifically retaining no memory of Ji Linglu or their life together. Medical experts explain that the brain may have suppressed memories associated with intense emotional stress as a self-protective mechanism. Gu Yu views Ji Linglu as a stranger and is suspicious of her presence, suspecting she is a scammer sent by his family. His mother and the doctors decide to conceal the truth to avoid further trauma, introducing Ji Linglu as a blind date arranged by his mother. This forces Ji Linglu into the painful position of having to win back the husband who remembers everything except her.

Ji Linglu attempts to reconnect with Gu Yu, trying to recreate their past romance under the guise of a courtship. She brings him meals, dresses elegantly to catch his attention, and tries to engage him in conversation. However, Gu Yu remains cold and distant, treating her with the same aloofness he shows strangers. He explicitly tells her not to waste her time on him, stating he has no intention of marrying. Despite his rejection, Ji Linglu is supported by her family and friends, who encourage her to persist. She continues to visit him, determined to make him fall in love with her again, unaware of the depth of the emotional chasm created by his memory loss.

The story takes a further turn when Gu Yu is discharged from the hospital and moves into a separate apartment, distancing himself from the family home and Ji Linglu. He resumes his work with intense focus, creating physical and emotional distance. Ji Linglu discovers his new residence and attempts to visit him at his company, but he remains unreachable and indifferent. The narrative highlights the stark contrast between the loving husband she knew and the cold stranger he has become. As Ji Linglu navigates this new reality, she must balance her love for Gu Yu with the painful rejection he offers, while the secret of their true relationship hangs in the balance, waiting for the moment when his memory might return or their connection might be rebuilt from scratch.
