After joining a medical device manufacturer, I went on a day trip with senior Kimura to talk business in a rural area. I have been in love with a beautiful, kind, and capable senior for a long time. However, my feelings for my married senior could not come true. Even so, I couldn't contain the excitement in my heart when I went on a business trip alone, but important business negotiations did not go smoothly and I decided to stay hastily. After that, I managed to stay alone in an empty room in a business hotel that I found.
