Dressed as a Cannon Fodder White Moonlight, I Attracted a Big Shot from the Capital Circle

Shen Nanxing, a patient with congenital heart disease, dies after staying up late reading a web novel titled "Wrong Love, Substitute, Young Master of a Rich Family, Take It Easy with the Spoiling." He transmigrates into the body of the novel's cannon fodder character, who shares his name. In the original story, this Shen Nanxing is the "white moonlight" of three childhood friends: Fu Chengyu, Zhou He, and Xia Zimu. While these men publicly revere the original Shen Nanxing, they secretly pursue Lin Bai, a substitute who resembles him, eventually building a harem around him. The original character discovers his fiancé Fu Chengyu's infidelity with Lin Bai, overhears their intimate conversation, and dies of a broken heart on the operating table. Shen Nanxing, now inhabiting this body, is determined to avoid the tragic fate of the original character and escape the toxic entanglements of the novel's plot.

Upon waking in the hospital, Shen Nanxing is cared for by his loving family, including his overprotective older brother Shen Chuanqiong and his doting parents. The warmth of his new family contrasts sharply with the cold manipulation he expects from the novel's male leads. Shen Nanxing attends Beijing University, where he tries to maintain a low profile. His first encounter with Lin Bai is accidental; Lin Bai trips and falls, blaming Shen Nanxing for not helping him, which plants a seed of resentment in Lin Bai. Shen Nanxing also reunites with Zhou He, a childhood friend and one of the novel's love interests, but deliberately distances himself to avoid the fate of a "green tea" victim. Zhou He is confused by Shen Nanxing's coldness, while Shen Nanxing remains wary of his role in the impending harem drama.

A pivotal moment occurs when Shen Chuanqiong takes Shen Nanxing to a bar to meet his friends, including Su Chen and Fu Zhiyuan, Fu Chengyu's powerful uncle. Shen Nanxing is immediately struck by Fu Zhiyuan's imposing presence and handsome appearance. Despite his initial wariness, Fu Zhiyuan shows a gentle side, giving Shen Nanxing an expensive rose brooch and nicknaming him "Xing Bao." This unexpected kindness creates a complex dynamic, as Shen Nanxing recognizes Fu Zhiyuan as a key figure in the novel who remains unaffected by Lin Bai's charms. Meanwhile, Fu Chengyu continues to visit Shen Nanxing, attempting to maintain their engagement, but Shen Nanxing grows increasingly distant and suspicious of his intentions.

The conflict escalates as Lin Bai actively pursues Fu Chengyu, using his resemblance to Shen Nanxing to manipulate him. Fu Chengyu, torn between his engagement and his growing obsession with Lin Bai, becomes erratic and aggressive towards Shen Nanxing. During a confrontation on campus, Fu Chengyu grabs Shen Nanxing roughly, leading to a public scene. Xia Zimu, another childhood friend, intervenes to protect Shen Nanxing, revealing his own complicated feelings and rivalry with Fu Chengyu. Shen Nanxing finds himself caught in the middle of these intense emotions, seeking a way to break off the engagement without causing further drama or endangering his health.

As the story progresses, Shen Nanxing navigates the treacherous waters of the novel's plot, trying to expose Fu Chengyu's true nature while protecting himself from the emotional manipulation of the male leads. He forms an unexpected bond with Fu Zhiyuan, who seems to offer a safer alternative to the chaotic relationships surrounding him. The narrative explores themes of identity, family loyalty, and the struggle to escape a predetermined tragic fate. Shen Nanxing's journey is one of self-preservation, as he attempts to rewrite his destiny in a world designed for his suffering.

The tension between Shen Nanxing and the novel's protagonists intensifies, with Lin Bai's schemes becoming more apparent. Shen Nanxing's health remains a critical factor, forcing him to balance his desire for freedom with the physical limitations imposed by his condition. The story sets the stage for a confrontation where Shen Nanxing must decisively break free from the engagement and the manipulative influences of Fu Chengyu and Lin Bai, potentially finding solace in the steadfast support of his family and the mysterious attention of Fu Zhiyuan.
