The Shiina couple had a good relationship when they first got married but after a few years, they became completely cold towards each other. My wife, Yuna, had been living a boring daily life without any married life for over a year. At that time, my husband invited me to go to a hot spring for the first time in a long while. Yuna, who wanted to improve her life, readily agreed. And on the day of the trip, Yuna arrived at the inn with vague expectations, but she did not realize that her husband's thoughts were bolder and more vulgar than she could imagine.
