Married Couple Swap

Reiji and his wife Kanade arrive at a traditional inn for a relaxing vacation, accompanied by their close friends Kosuke and Asuka. The two couples anticipate a peaceful getaway together, but the atmosphere shifts dramatically on their very first evening. During dinner, an unexpected and heated argument erupts between them, shattering the tranquility of the trip and exposing underlying tensions neither couple anticipated. In the wake of the confrontation, Asuka abruptly pulls Reiji away from the table and leads him to her private room, leaving their respective spouses behind. The sudden separation forces Reiji into a deeply uncomfortable position, caught between loyalty to his marriage and the impulsive actions unfolding around him. While isolated with Asuka, he becomes acutely aware of sounds drifting through the walls—most notably, the restless, unsettled sighs of his wife Kanade in the adjacent space. Those faint noises serve as a constant reminder of the emotional turmoil now threatening both relationships, transforming what was meant to be a simple holiday into a complicated web of temptation, guilt, and fractured trust.
