It was the winter of five years ago, I committed the sin of infidelity. At that time, Yuzuru-kun, who was unfaithful to his husband, shook his body and sincerely expressed his favor to me, who was injured. I wanted to fill my loneliness, but even though I knew it was bad, I responded to that thought. A boy has grown old. Every time he was asked, his flickering sense of guilt was overwhelmed by intense sexual desire. At first, I intended to beat my husband to death, but my feelings for him grew stronger day by day.
