In a world where heroines of yandere novels reincarnate to escape obsessive male leads, Chen Manzi returns to her past life determined to avoid Huo Hanting, a cold and controlling third-generation heir known as the demon king of Deep City. In her previous existence, Chen Manzi had been trapped by Huo Hanting’s pathological obsession, leading to her family’s ruin and her own imprisonment. Seeking a safer path, she aims to align herself with Gu Huai, the gentle second male lead who is destined to become a tech tycoon. However, her plans are upended when she accidentally shoves her colleague, Fu Yu, into Huo Hanting at a welcome banquet. Instead of Chen Manzi, it is Fu Yu who catches Huo Hanting’s attention, leading to an unintended kiss that alters the course of fate.
Fu Yu is not merely a passive victim of circumstance; she is a top-ranked career-type Quick Transmigration repairer tasked with stabilizing a collapsing narrative. Her mission is to raise Huo Hanting’s affection score and prevent the world from disintegrating due to the heroine’s rebellion. Equipped with a unique golden finger that enhances fertility and triggers automatic bonding effects, Fu Yu approaches her task with clinical detachment, viewing Huo Hanting as a difficult subject to be managed rather than a romantic partner. Despite her initial reservations, she finds that Huo Hanting’s affection meter, which should be difficult to raise, maxes out almost instantly upon their first physical contact.
As Fu Yu integrates herself into Huo Hanting’s life, she accepts a lucrative offer to join Huo Corporation, moving from a rival firm to become his personal senior researcher. Huo Hanting, whose psychological trauma stems from his father’s infidelity and his mother’s tragic death, finds himself inexplicably drawn to Fu Yu’s calm demeanor and plain appearance. Unlike the women who previously sought his wealth or resembled his mother, Fu Yu treats him with a mix of indifference and authority that captivates him. He clears out her apartment building to eliminate male tenants, dedicates a private lab to her, and ultimately proposes marriage after a trip to a spiritual temple, seeking a legitimate bond to keep her close.
Chen Manzi, meanwhile, struggles with her new reality. She attempts to secure a relationship with Gu Huai, believing him to be the safe alternative to Huo Hanting. However, her jealousy and insecurity lead her to mistreat Fu Yu, accusing her of being a gold digger at a charity gala. This confrontation draws the attention of Aunt Xun, Huo Hanting’s aunt and a powerful businesswoman, who fiercely defends Fu Yu and punishes Chen Manzi’s circle. The incident marks the beginning of the Chen family’s downfall, as Huo Hanting, though initially indifferent to Chen Manzi, enforces a business blockade against her company due to her disrespect toward his wife.
The narrative deepens as Fu Yu discovers that Huo Hanting’s obsession is linked to a pen pal from his military days, whose comforting letters he cherished. It is revealed that in the original timeline, Fu Yu had written those letters for Chen Manzi, creating a false connection that fueled Huo Hanting’s initial fixation on the heroine. In this revised timeline, Fu Yu’s own handwriting on a simple test paper triggers Huo Hanting’s memories, solidifying his belief that she is his destined partner. As Fu Yu works to lower his darkening value through strategic emotional management, she navigates the complexities of his possessive nature while maintaining her professional goals. The story culminates in Huo Hanting publicly declaring his love for Fu Yu during a grand proposal, cementing their union and leaving Chen Manzi to face the consequences of her past-life choices as her family crumbles under the weight of their own failures.
