It's been two years since I married my wife. Our days were ordinary, yet I felt happy... or at least, I did until I met her. On the surface, my relationship with my wife was going well. But then she asked me, "You and your wife Naoki love each other, right?" I replied, "Of course." Then she said, "But... emotions and physical desire are different things, aren't they? As long as it doesn't get found out, it's not really cheating." And then she asked further, "But... can you really keep enduring only Naoki for the rest of your life?" When faced with such temptation, is there any man who could resist? What would you do?
