I have almost no experience with women, and I don't have many friends. I was just having a boring day. One day, I was forced to have a physical relationship with Yui, a married woman at my part-time job. At first, I was only half-joking, but I said that I was sexless and frustrated even though I was a newlywed ... I had sex with Yui. From that day on, Yui and I became in a relationship where we sought each other.
