I, Rintaro Tsukiyuki, have stopped trusting people since that day. Back in high school, I had a crush on Mikku Saeki and confessed my feelings to her. Even after becoming a working adult, we continued our relationship.  Those were the days when I worked overtime to save up and buy her an engagement ring. Sometimes, my boss told me to go home early, but when I got back to my place, I saw a video stream that I had forgotten to turn off in the morning. In that live stream video, I witnessed a vivid scene of Mikku and my coworker, Ren Kagayama, betraying me in my own room. Despair overwhelmed me. I thought about ending my life due to their betrayal, but the video I had casually uploaded for my hobby had unexpectedly surpassed 500,000 views, far exceeding my expectation of just 100 views. Finding a reason to live, I decided to seek revenge on the two of them. I made up my mind to carry out a real-life netorare (cuckoldry) live stream.
