After secretly checking my wife's phone, I discovered she was having an affair with my classmate. (Shiramine Miyu ADN-550)

My wife recently started using a cell phone, "and it's basically only used to contact her husband..." Although she wasn't actively changing phones, she became addicted after switching. At first, I thought it was just temporary, but... she couldn't put it down for a single day, and it started to seem strange. While I didn't suspect her, I noticed deleted messages in her chat history, so I asked someone to help me recover the messages from her contacts. It turned out my wife was having an affair. And the other man was my classmate.
