When I entered college, I moved to the city. In the morning, I opened the door to take out the trash.

"......Oh, Yuuto-kun. Good morning."

A married woman who lived next door――I exchanged greetings with Kagatsuka Shiho.

Loose shoulder-length hair. A cute and beautiful woman with nice figure. I mean, after all, you could see it from her clothes, a nice hourglass-shape body line. If a man were to walk pass Shiho-san in the city, he would surely want to look at such beauty. Exactly the embodiment of the men's ideal image of a woman.

(I could not believe that someone is married to this woman, what did her husband do in his previous life?)

One day...... I saw her――Shiho-san and an unfamiliar man, entering a love hotel――.
