The Handsome Salesman At My Office Is My Ideal Master

Hajime Yanase is a plain businessman who's pretty quiet at work. However, he's actually a hardcore submissive guy who often fishes online for men to hook up with, but usually ends up unsatisfied.
One day, his coworkers spot him leaving a shady hotel with one of his hookups. Rumors about him spread quickly, leaving him gloomy and alone at a company party. While everyone is making fun of Yanase, Haru Mitani, an extroverted and handsome guy from the sales department, starts chatting with him, confiding that he, too, is gay and wants to blow off some steam!
Even though Yanase knows their arrangement is just physical, he can't help feeling satisfied from their perfect chemistry in bed. At the same time, as they see each other more and more, Mitani's possessive nature starts to grow stronger...
This is the story of a handsome, big-shot, and dominant salesman and a seemingly-quiet, introverted businessman who's actually quite wild in the bedroom!
