The person I had a one-night stand with turned out to be my good friend’s older brother

Song Wenjing is a young man from a wealthy family who has always considered himself heterosexual. His life takes an unexpected turn after a night of heavy drinking, during which he spends the morning with a man he cannot fully recall. The only tangible evidence of the encounter is a button from a shirt and vivid, confusing memories of being the dominant partner. Despite his initial shock and confusion, Song Wenjing decides to investigate the identity of the stranger. He drives to the home of his friend, Shi Bai, to meet Shi Bai’s older brother, Shi Shaoyu, a reserved and successful businessman. Upon meeting Shi Shaoyu, Song Wenjing recognizes the red marks on the man’s wrists and realizes that Shi Shaoyu is the man from the previous night. Shi Shaoyu, displaying a sly and flirtatious demeanor, does not deny the encounter. Instead, he invites Song Wenjing into his private space to repair the button on his shirt, effectively initiating a complex and charged dynamic between them.

The relationship between the two men evolves rapidly from a drunken mistake into an intense romantic and physical entanglement. Shi Shaoyu, who appears reserved on the surface, reveals a mischievous and seductive side when alone with Song Wenjing. He teases Song Wenjing about his sexual orientation and experience, challenging Song Wenjing’s self-perception. The tension escalates when Song Wenjing discovers Shi Shaoyu being harassed by Chen Wei, a businessman with ties to Song Wenjing’s family, at a private club. Chen Wei had drugged Shi Shaoyu’s drink with the intent to exploit him. Song Wenjing intervenes violently, beating Chen Wei and his associates despite sustaining injuries himself, including a blow from a baseball bat. He takes care of the intoxicated Shi Shaoyu throughout the night, solidifying his role as a protector and deepening their emotional bond. The incident with Chen Wei serves as a catalyst, pushing Song Wenjing to openly pursue Shi Shaoyu and care for him domestically, cooking meals and ensuring his well-being.

As their relationship progresses, external obstacles and internal doubts test their connection. Shi Bai, seeking to provoke a reaction, arranges for Shi Shaoyu to meet with a childhood friend, Shen Cheng, at a hotel. Song Wenjing, driven by jealousy, confronts them but is reassured by Shi Shaoyu’s calm demeanor and eventual explanation that it was a ruse. Later, at a business event, Shi Shaoyu is targeted by another host who attempts to drug him. Song Wenjing intercepts the drugged wine and drinks it himself to protect Shi Shaoyu, leading to a night of intense intimacy where the drug’s effects blur the lines between coercion and desire. Following this, Song Wenjing’s family discovers his involvement with Shi Shaoyu, resulting in a physical reprimand from his father. However, the family’s anger is tempered by the realization that Shi Shaoyu is not being mistreated but is rather an active participant in the relationship.

The narrative reaches its climax during Shi Shaoyu’s birthday celebration. Song Wenjing prepares a elaborate surprise, tying himself up with Shi Shaoyu’s tie and presenting himself as a gift amidst a sea of flowers. He confesses his genuine feelings, asking if Shi Shaoyu likes him in return. Shi Shaoyu reciprocates, acknowledging that he has never felt such strong emotions for anyone before. The couple spends the night together, and the following morning, Song Wenjing is discovered by Shi Shaoyu’s parents. Rather than rejecting the relationship, Shi Shaoyu’s parents accept Song Wenjing, expressing relief that their son has found someone he loves. The story concludes with the arrival of Shi Bai and Shen Cheng, whose own romantic entanglement mirrors that of the main couple, hinting at a future where both families navigate their new dynamics with a mix of shock and acceptance.
