When my husband's father was transferred overseas, my husband and I agreed to take in his younger brother, Yuzuru, who was still in high school. I became increasingly worried as I noticed he was neglecting his studies, completely obsessed with an idol group and spending every day obsessively supporting them. Unable to contain my frustration, I secretly threw away his cherished fan merchandise. This act triggered Yuzuru's explosive rage—and marked the beginning of a nightmare. Trembling with anger, Yuzuru brought his idol friends to our home, refusing to accept my apologies. From that point on, they turned our house into their gangbang playground, severely disrupting our daily lives. Amidst the chaos, I struggle to understand his feelings and search for a way to repair our broken relationship.
