In a corner of Shinjuku, there is a run-down hotel called Sankai Hotel, which used to be a gay-only Hatten inn that is quite famous in this world. One day, a man arrived who had inherited the land and building of the hotel from a distant relative of his. The man's wife ran away with him, he was laid off from his job, and he was in the depths of despair. He was thinking of starting his life over by running this hotel. However, the man was straight, so of course he didn't know about the actual situation at this hotel. What the man saw there were customers who were enjoying being gay and enjoying sex with whomever they wanted.
