Two years after I entered the workforce, I went on a day trip with my older colleague, Ueba-senpai. She was in love with her senior, who was beautiful, good at work, and the ideal boss that everyone envied. My feelings for my senior, who is married, are unlikely to come true, but I couldn't stop my heart pounding as we went on a business trip together. However, business negotiations with business partners don't go well and he ends up having to stay overnight. Stayed overnight due to a big festival.
