You're in Trouble, Mister!

To celebrate Christmas, Hayan prepares a surprise party for her boyfriend who has moved into the luxury apartment ‘Royal Palace’. She lets herself in using his birthday as the password, but the lights are off. Hayan finds her boyfriend asleep in bed and proceeds to pleasure herself with him. Although he seems different from usual, she thinks, ‘Well, who cares. As long as it feels good.’ Just as she is about to climax, she opens her eyes and meets the gaze of a strange man who has just woken up. Hayan becomes excited by the immorality of sleeping with a man who is not her boyfriend, and Ja-eon, who was unexpectedly assaulted in his sleep, also gives in to her seduction, leading to a passionate one-night stand.
