When did the gears go crazy...? Ten years ago, when she married her husband, her older brother Tatsuya and younger brother Kazuya were bright and sociable children. However, after his older brother failed his exams, he began to withdraw at home, and his younger brother Kazuya gradually became dark and distorted. And one day, Kazuya-kun asked me for sexual treatment with dark and cloudy eyes. I tried to comfort him, who didn't know what would happen if he didn't go on like this, but his older brother, Tatsuya-kun, saw me.
