For 21 years, my married life with my wife, who had always supported me, was peaceful and fulfilling. But one day, everything changed when my younger brother lost his job and moved in with us while searching for work. From that moment on, I noticed a clear shift in my wife's behavior, and I began to sense that something was terribly wrong. Growing increasingly frustrated and suspicious, I pretended to be drunk and tried approaching my wife in front of my brother, only to be harshly rejected—an incident that deeply shook me. That night, I witnessed my wife being trained as a masochist by my brother, exposed and humiliated intensely outdoors, visibly aroused by the experience. I was crushed by overwhelming shock and jealousy. My trust in my wife shattered instantly, and I fell into days of confusion and inner turmoil.
