Rin to Shita Tsuma wa, Hitoshirezu Midarazuma e to Ochite

Hirokazu and Madoka, who met in the same seminar at university , were leading a peaceful life as a dual-earner couple. The only complaint is that his wife earns more money than him, and that their nightly activities are a little too boring. But recently, there was something that bothered him. A chance encounter with Shogo Makino, the man who used to be interested in Madoka. This brings back memories that he had been trying to avoid remembering. A hint of anxiety sprouts in his daily life. How will that man be involved in the days to come? Or will nothing happen at all and things will continue to go on peacefully?
