Two years after I became a member of society, I was on a day trip with my senior Sumi. 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 negotiations with business partners do not go well and they end up staying in a hurry. Due to the big festival, we couldn't find a place to stay, so we managed to find an empty room and ended up staying there alone.
