Two years after I became a member of society, I came on a one-day business trip with my older Ichino-senpai. - She was in love with her senior, who was beautiful, could work, and was the ideal boss that everyone envied. - Her feelings for her senior, who is married, should not come true, but she couldn't stop pounding on a business trip alone. However, business negotiations with business partners did not go well and he ended up staying overnight in a hurry. Due to the influence of the big festival, we couldn't find a place to stay, so we decided to stay alone in one vacant room that we managed to find.
