Accidentally Married a Ghost

Ruan Xinyuan is a college freshman who, since childhood, has been told by his grandmother that he suffers from a rare fate condition requiring him to marry a specific man before turning eighteen or face death. His grandmother has spent years fortune-telling to identify this destined partner, providing three precise conditions: the man must have a mole on the back of his neck, be ten years older, and share the same birth date and month. Despite being a staunch materialist, Ruan Xinyuan begins to take the prophecy seriously after experiencing recurring nightmares of burning and intense chest pain that medical tests cannot explain.

One day, Ruan Xinyuan attends a lecture at a neighboring university where he encounters Qi Xun, an associate professor of ancient history. He immediately notices a mole on the back of Qi Xun's neck. Through online research, he discovers that Qi Xun was born on New Year's Day, matching his own birth date, and is twenty-eight years old, exactly ten years his senior. Realizing all three conditions are met, Ruan Xinyuan, encouraged by his friend Qiao Siming, decides to propose directly to save his own life. He purchases ninety-nine red roses and approaches Qi Xun after class, declaring his love and asking to marry him immediately.

To Ruan Xinyuan's astonishment, Qi Xun agrees without hesitation. The story reveals that Qi Xun is actually a ghost king from the Southern Yan Underworld who has lived for over nine hundred years. He recognizes Ruan Xinyuan as his reincarnated partner from a past life and has been searching for him across centuries. Qi Xun's swift agreement stems not from parental pressure as he claims, but from his ancient desire to reunite with the soul he has loved for centuries. After their meeting, Qi Xun consults with underworld officials and learns that Ruan Xinyuan's fate records are blank, indicating his soul is extraordinary and not bound by normal reincarnation rules.

Ruan Xinyuan and Qi Xun begin communicating through WeChat and arrange to discuss marriage details. They meet for dinner where Qi Xun explains his family is pressuring him to marry, creating a mutually convenient arrangement. During their conversation, Ruan Xinyuan experiences another episode of chest pain but manages to endure it. Qi Xun drives him back to campus, returning the romantic gesture by giving him ninety-nine white roses. Ruan Xinyuan introduces Qi Xun to his roommates and informs his family that he has found his destined partner. His grandmother calculates an auspicious date for the marriage certificate.

On the chosen day, Ruan Xinyuan and Qi Xun go to the civil affairs bureau to register their marriage. Along the way, they discuss their families and future plans. At the bureau, they encounter Song Min, a colleague of Qi Xun's, whom Qi Xun introduces as his fiancé. After receiving their marriage certificates, Qi Xun asks Ruan Xinyuan to change how he addresses him, suggesting the term "hubby." The story ends with Ruan Xinyuan flustered by the intimate address, while Qi Xun watches him with deep affection, hinting at the complex supernatural relationship that lies ahead between the mortal student and his ancient ghost husband.
