A long-awaited getaway with childhood friends takes a dangerous turn when Yu Seol-Ah wakes in the dark to a touch she shouldn’t want, only to realize it belongs to Lee Tae-Geon, her best friend’s boyfriend. Caught between sleep and reality, her body reacts before her reason can catch up, blurring lines she’s spent ten years respecting. One forbidden moment is all it takes to threaten their friendship, their trust, and perhaps...to give her everything she's ever wanted.
