On a Friday night, while drinking with my friends from my school days at our usual izakaya, the topic turned to my wife. She's such a beautiful woman, surely she's had a cheating streak or two? That's what they were saying. I know I'm being self-promoting, but my wife is certainly pretty good-looking, and people around her are often jealous of her. However, I find it hard to imagine her, who is rather shy and withdrawn, playing around with men. But... what if... I laughed it off, trying to shake off the unpleasant image that was about to come to my mind, and took a sip of beer, but I was overcome with such a strange excitement that I even forgot the taste of the alcohol going down my throat.
