I work at a food company and I really dislike my boss, Kotani-senpai. He scolds me for my innovative presentations, calling them nonsense, and often scolds me for being uncooperative and having a bad attitude. That day, Kotani-senpai called me up to the stairs, and as we were arguing as usual, he offered to teach me manners from scratch and invited me to dinner. However, Kotani-senpai chose a family restaurant... I drank like crazy while complaining. I lost my memory after that, and when I woke up the next morning, Kotani-senpai was naked next to me...!?
