"Today, Mahiro has his back to me and is looking at his phone." I'd been married to Mahiro for five years, and we'd been in a relationship where we were boss and subordinate 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 fiddling 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'd never felt before, rather than anger.
