Hideaki, a man living in an apartment building. One night, a couple living next to each other heard an unpleasant voice from the window. Although it is not so close, Hideaki gets excited by imagining the splendid figure of his wife Erika who somehow knows. I suddenly got a chance to see Hideaki, who was wondering if he could do something like Erika and H! Just because I always cleaned the common parts, I went to deliver my thanks and Eriko in Nobra appeared.
