Gu Xingnian and Fu Beichen have been in a hidden marriage for three years, bound by a contract arranged by Fu Beichen's dying grandmother. Their relationship is strictly transactional, with intimate encounters limited to specific days of the month at Nianxin Pavilion, a residence filled with white lilies that Gu Xingnian loves but which was ultimately built for Fu Beichen's first love, Jiang Kexin. As the three-year term expires, Gu Xingnian decides to end the marriage and initiates divorce proceedings. However, her plans are shattered when she discovers news of Fu Beichen's lavish birthday celebration for Jiang Kexin in F Country, revealing that the pavilion and his affection were never truly hers. Heartbroken and realizing the depth of his indifference, she proceeds with the divorce, offering to leave with nothing in exchange for a clean break.
Tragedy strikes shortly after when Gu Xingnian suffers a miscarriage, having been six weeks pregnant without knowing it. The medical examination reveals she had been taking contraceptive pills, which were secretly administered to her, likely by Fu Beichen to prevent pregnancy for Jiang Kexin's sake. Devastated and enraged, Gu Xingnian undergoes a painful, anesthesia-free surgery due to a genetic allergy, vowing to uncover the truth behind her lost child. Meanwhile, Fu Beichen, unaware of her hospitalization and the miscarriage, remains focused on Jiang Kexin, whom he believes saved his life four years ago in F Country. He is oblivious to the fact that the woman who actually rescued him was someone else, and he continues to pour his affection into Jiang Kexin, even arranging for her to star in a major drama production.
The narrative shifts with the return of Lu Lie, a powerful business magnate and Gu Xingnian's former senior from her PhD days. Lu Lie had left her three years ago after she chose the contract marriage, but he returns now that her agreement has expired. He reveals that Gu Xingnian is the legendary biologist known as "God N," the creator of a groundbreaking cancer treatment equation that changed the medical world. Lu Lie invites her to return to the scientific arena, offering her a new beginning and a partnership to reclaim her former glory. Gu Xingnian agrees, shedding her submissive persona and preparing to re-enter the global medical summit alongside Lu Lie and their former lab team.
Tensions escalate when Fu Beichen encounters Gu Xingnian with Lu Lie at an exclusive club. Jealous and confused by her sudden confidence and association with another man, he confronts her, attempting to extract information about God N's identity in exchange for financial compensation. Gu Xingnian refuses, coldly rejecting his advances and asserting her independence. The confrontation is interrupted when Jiang Kexin is taken hostage by a deranged fan, leading Fu Beichen to rescue her and further cement his devotion to the actress. Unbeknownst to him, Gu Xingnian is present but chooses to withdraw, watching him protect Jiang Kexin with a mix of bitterness and resolve.
As Gu Xingnian prepares to launch her comeback, she begins investigating the circumstances surrounding her miscarriage, suspecting foul play within the Fu family. Lu Lie supports her efforts, establishing a new headquarters in Hai City to compete with Fu Beichen's empire. The story sets the stage for a complex rivalry between Fu Beichen and Lu Lie, while Gu Xingnian navigates her dual identity as a hidden genius and a woman seeking justice. Fu Beichen, initially dismissive of her, begins to feel an inexplicable sense of loss and regret as he realizes he may have underestimated the woman he was eager to divorce. The path ahead involves Gu Xingnian reclaiming her power, exposing the truth about the contraceptives, and potentially reconciling with or moving on from her past, all while Lu Lie waits to see if she will choose to soar beside him in the world of science and business.
