Yuu has moved to Tokyo and is looking for an apartment. I happened to find a cheap lodging house without doing much research and happily moved in. “It feels like something retro ~ Showa era.” Yu, who was brainwashed while enjoying the intense Ryo ΓùÅ, ended up bringing in his friend Sena as the landlord told him to do. Every night, the two of them are bound and trained.
