Lost Boundaries on the Journey

On a long-distance night bus, a dimly lit cabin is filled with a secret, restless tension. In Episode 1, a young couple in the back row secretly fool around under the cover of their clothes; the boyfriend finishes too quickly, leaving the girl beside him unsatisfied and still catching her breath. After witnessing everything, the middle-aged man in the next seat forcefully steps in, using the darkness and the jolting motion of the ride to make bold demands, sending the whole journey sliding completely into an out-of-control abyss of taboo.
