As a lonely ronin student living alone day after day, my mother was my emotional anchor, gently supporting and comforting me. However, one day, I accidentally witnessed her passionately entwined with another man inside my parents' bedroom. In that instant, a deep rift tore through my heart, warping my feelings toward her. From that night on, I became consumed by an overwhelming urge, driven by an uncontrollable desire to possess her myself.
