I work for an outdoor shop company, and I was on a day trip with my senior, Rukawa. I was in love with my senior, who was beautiful and good at work and was the ideal boss that everyone envied. There is no way my feelings for a married senior will come true, but the excitement of a business trip with just the two of us didn't stop. However, business talks with business partners drag on and he misses the Shinkansen on his way home. We suddenly decided to stay overnight, but somehow we managed to find an empty room and ended up staying alone.
