At the accommodation of an affair trip...

I'm Yui, 27 years old. The other man is Kurokawa, my former boss. Kurokawa has a wife and child. We are having an affair. I was embraced by Kurokawa, even though I knew we would never be together. However, in an effort to forget about it last year, I married an arranged man. But I couldn't forget Kurokawa. And so, I came to this inn today. This was the last trip where I decided to say goodbye. However, something happened that stopped me from feeling that way...
