It's been 3 months since I was assigned to work alone and live apart from my wife and child, and when I got used to this life ... I met the married woman next door, Kyou, and fell in love at first sight. Even though I was tormented by guilt for my wife, I couldn't get An-san out of my mind. "Shall I borrow you a shower?" he asked me one day, who was sweaty and had lost his keys. - I was spoiled by the favor and decided to stay at Kyou's house, but I lost my reason in An's defenseless room clothes, which usually wear long skirts.
