Mako, who works part-time, is kind and beautiful to everyone, and is looked upon by those around her with envious eyes, but she is dissatisfied with her husband who doesn't look at her as a woman. On the other hand, Yoshino, who works part-time at the same workplace as Mako, is not good at being a good-natured man and is branded as a bad guy, but he secretly admires Mako, who treats her without any discrimination. When the two of them bit each other's gears... passion lights up and love accelerates!
