His wife's stepdaughter was raped by her stepfather while her mother was away

Mahiru, a female university student whose mother remarried and started a new life with her father-in-law. Mahiru used to have a forgiving heart towards her extremely kind father-in-law, but one day everything changed completely. I watched my father-in-law devour Mahiru's underwear from the washing machine. But I don't want to see my mother sad. From that day on, Mahiru was separated from her father-in-law, but her grandmother fell ill and her mother had to return home for a while. And when Mahiru tried to escape to a friend's house, her cunning and lustful father-in-law intervened.
