I was forced by my company to take in a new intern named Yuuki, but he was an antisocial loser who couldn't do anything right. As his supervisor, I was already frustrated. Things got worse when I noticed he started hitting on my wife, Airi, and acting disrespectfully, which only fueled my anger. Soon, I began noticing subtle changes in Airi's behavior and attitude—something felt off. A terrible suspicion crept in: could my wife actually be having an affair with Yuuki? Today, I planted hidden cameras around the house, invited Yuuki over, and left the house under the false pretense of running errands—to catch them in the act.
