It's been two years since I joined a manufacturer of beauty equipment for women, and I'm still a failure who keeps making mistakes, but it's thanks to my senior, Kato, that I haven't given up and can continue working. She's beautiful, kind, and good at her job... I've come to admire her as the Madonna of the company. This time, I decided to go on a day trip with her just the two of us. However, because of my mistake, we suddenly had to stay overnight... and we managed to find a vacant room and stayed there just the two of us...
