"Doremi" is a single-family house that runs quietly in a rural town with a lake. On the surface, it is a guest house that doubles as a residence for employees, but it is also a sex shop that retains the remnants of the Showa era. Sora and Shido, who work there, worked happily every day. However, the inn was in danger of eviction due to the customs purification administration and the redevelopment plan. When he is about to lose his place to return, Sora realizes his feelings towards Kaname, who is also his parent, and feels confused.
