Otani and Tanabei are a couple in a relationship. It was only after Otani had a relationship that he admitted that he was already married, which made him feel ashamed, but Otani then explained that he married each other on the orders of his father, and that his wife was passionate and drunk, but at least he was able to hide his gay identity. One day, after he went to Otani's home to meet his wife, Otani unexpectedly invited him to move into their home as their roommate.
