Due to company policy, we decided to accept an intern named Yuki, but he is an introvert and can't do his job, and I, the person in charge of training, was annoyed with him. What's more, he keeps bothering my wife, Airi. Meanwhile, I notice that Airi's behavior is changing day by day. I have a bad feeling, but my wife might be having an affair with Yuki... So today, after setting up a surveillance camera, I called Yuki to my house, saying that I had something to take care of, and decided to leave the house...
