Oh no! Drunk last night, I accidentally wandered into my ex-boyfriend's room.

After a night of drinking, Lin Qian wakes up to discover she has accidentally spent the night with her ex-boyfriend, Lu Beiting, a powerful and ruthless tycoon in Beijing's elite circles. Despite his notorious reputation as a ladies' man, Lin Qian had secretly harbored a crush on him during their clandestine college romance three years ago. However, she has since tried to move on and distance herself from him. When they cross paths again at their high school reunion, Lu Beiting's intense passion is rekindled, and he refuses to let Lin Qian go, pinning her against the wall and demanding to know what she is hiding from. As he forcefully kisses her, Lin Qian is forced to confront the lingering emotions between them, and Lu Beiting's desperate question - "Can we not break up?" - threatens to upend her attempts to escape their complicated past.
