I worked at a food-related company where I deeply disliked my supervisor, Senior Kotani. She dismissed my innovative presentations as nonsense and constantly berated me for my lack of cooperation and poor attitude. That day, she called me to the stairs, and as usual, we argued. When I offered to teach her some manners, she invited me to dinner. However, she chose a cheap family restaurant, and I grumbled while downing drinks. From there, my memory goes blank, and the next morning, I woke up to find Senior Kotani naked beside me…!?
