The wife's stepdaughter was raped by her stepfather

My mother loves a man who has a wife and children and takes care of me. Due to strong opposition from my parents, my mother left home and raised me alone. I was poor and had to travel around in many different lands, but I finally settled down to live in this land … It's been two years since then. I became a university student and my mother remarried the landlord. I want my mother to be happy. …… But I was suddenly raped by my father-in-law.
