After Sending the Love Letter to the Wrong Person, I Got Entangled with a Notorious Rich Bad Boy from Beijing's Elite Circle

An Li, an adopted daughter of the wealthy Duan family, has secretly admired the elder brother Duan Xingning for four years. Known for her stutter and timid nature, she works as his assistant in his music band. On the night of Duan Xingning’s birthday banquet, An Li, emboldened by alcohol, attempts to confess her feelings by delivering a love letter. However, due to a mix-up, she enters the wrong room and mistakes the younger brother, Duan Zhuo, for Duan Xingning. Duan Zhuo, a notorious playboy and the heir to the family business, takes advantage of her drunken state, and they spend the night together. The next morning, An Li wakes up beside Duan Zhuo and is horrified to discover her mistake. She pleads for secrecy, fearing the scandal will ruin her relationship with her beloved brother, but Duan Zhuo refuses to let her go so easily.

Duan Zhuo blackmails An Li into dating him, threatening to reveal the truth to Duan Xingning if she refuses. An Li is already in a precarious position, as she learns that Duan Xingning has an arranged fiancée, Wen Shuyi, who has recently returned from abroad. Despite her lingering feelings for Duan Xingning, An Li is forced to accept Duan Zhuo’s demands. Their relationship begins under duress, with Duan Zhuo constantly teasing and provoking her. He insists on calling her his girlfriend and wife, while An Li struggles to maintain her distance and protect her secret. The tension escalates when Duan Zhuo accompanies An Li to the hospital for her injuries, publicly claiming her as his wife in front of medical staff, further complicating her situation.

The conflict deepens when An Li attempts to steal back her love letter from Duan Zhuo’s room to eliminate the evidence of their night together. Duan Zhuo catches her in the act and uses the opportunity to further manipulate her, deleting all his female contacts to prove his “loyalty” and demanding she date him for three months. An Li reluctantly agrees to a shorter term, hoping to end the arrangement as quickly as possible. Meanwhile, Duan Xingning remains oblivious to the truth, treating An Li with a mix of professional distance and subtle care. Wen Shuyi, the fiancée, appears gentle and accommodating, but her actions suggest she may not be as innocent as she seems, particularly when she denies handing over An Li’s work schedule, leading to professional mishaps.

A significant turning point occurs during a magazine photoshoot for Duan Xingning. When the scheduled model cancels, the staff suggests An Li substitute for her. Duan Zhuo, witnessing the potential intimacy between An Li and his brother, intervenes aggressively. He not only protects An Li from a abusive manager but also steps in to take the photoshoot himself, refusing to let his brother be photographed with her. This act of possession draws attention and raises questions among the staff, though Duan Zhuo masks his motives with casual remarks about his girlfriend. The incident highlights Duan Zhuo’s growing jealousy and his determination to keep An Li away from Duan Xingning.

As the story progresses, the dynamic between the three characters becomes increasingly complex. Duan Zhuo continues to pursue An Li with relentless energy, challenging her feelings and forcing her to confront her true emotions. An Li finds herself torn between her long-held crush on Duan Xingning and the unexpected attention from Duan Zhuo. The presence of Wen Shuyi adds another layer of tension, as her role as the fiancée looms over An Li’s secret relationship. The narrative sets the stage for a dramatic confrontation, with An Li’s secret hanging in the balance and Duan Zhuo’s true intentions becoming clearer. The story moves toward a resolution where An Li must decide between her past affections and the new, complicated reality she has entered with Duan Zhuo.
