She was raped every day by her mother's second husband, an older man. (Shiraishi Momo, SAME-107)

My father passed away when I was young, and I've been living alone ever since. My mother works until late every day to support me, until a year ago when she remarried a businessman she met at her workplace. I want my mother to be happy... but lately she's been acting strangely, always talking to herself, and even lying to my father... like this every day.
