Kousuke and Yukio meet regularly to eat dinner together as buddies, but in Kousuke’s mind, their relationship is much more intimate and intense than Yukio could ever imagine. When Kousuke goes home, he can clearly see Yukio greeting him on all fours at the front door on a leash, complete with toys and bondage. He keeps his explicit fantasies a secret from Yukio in real life, but at home, he lives a second life with his beloved sex slave who once saved his life from a drunken man with a knife four years ago.
