The sound of Mother Misuzu echoed from inside the storehouse. A year after my older brother Shuichi's death, Mother suddenly began acting strangely. That night, as I passed by the storehouse, I witnessed a shocking scene. Inside, where there should have been no one else, Mother was discarding her clothes, growing increasingly aroused. Her bizarre behavior continued from that day on. Pitying her yet feeling helpless, I made a fateful decision in my heart.
