"Today, Mahiro has his back to me and is looking at his phone." I had been married to Mahiro for five years, and we were originally in a boss-subordinate relationship at the same workplace. We lived ordinary but happy lives. But one day, Mahiro started looking at his phone in bed. "I'm looking for a store." At first, I had no suspicions. However, the bright light of the phone caught my attention, so I peeked at Mahiro, who had turned his back to me and was playing with his phone. And I saw an unbelievable sight. A graphic message with a stranger. When I found out that my wife was cheating on me, I was surprised to feel an excitement I had never felt before, rather than anger.
