My name is Haruhara, I'm 30. My wife Miki is 26. We've been married for three years and have no children. About five houses away in our neighborhood lives an apartment building, where a man with a somewhat shady past lives, and who is supposedly a professional fighter. Being a herbivore, I'm not good with fights or arguments, so I try to stay out of it as much as possible. But then one day, when I came home from work, I found my wife completely naked in our bedroom, who I assumed had just been in the arms of fighter Ikeda...!
