Mahiro and I have been married for five years. We worked at the same company, she as my superior, and despite our ordinary lives, we were happy. But one day, I noticed her secretly looking at her phone in bed. At first, I didn't suspect anything—I was just bothered by the screen's glow. Without her noticing, I peeked over her shoulder. What I saw shocked me: explicit messages with an unknown man. Confronted with the reality that my wife was cheating, I felt not anger, but an overwhelming, unprecedented excitement.
