After finishing late-night overtime, I started drinking alone at a nearby izakaya when an office lady at the next seat struck up a conversation, and we quickly hit it off. As we talked about workday life, our connection deepened. When the topic turned to the late hour and last trains having ended, I boldly suggested continuing the night at my place. Surprised but gradually opening up, she agreed. Between an affair with a female boss at work, a chance encounter at a bar, and mistakenly guiding her to the wrong apartment through a back exit while drunk, this unfolds into a real-life cuckolding experience. A vivid portrayal of intense human drama capturing the raw, authentic moments of infidelity.
