Fuufu: Koukan: Modorenai Yoru
One couple attempts to stop the arrangement, only to discover that their partner has continued in secret. The other couple embraces the new dynamics, but with a coldness that lacks affection.

The first explicit scene is not triumphant or liberating. It is described with cold precision—mechanical movements, a wife closing her eyes as if focusing on a chore, the visiting husband noticing how different his friend’s spouse smells.
