Mahiru, a college student whose mother has remarried and started a new life with her father-in-law, had once harbored a forgiving heart towards her very kind father-in-law, but one day everything changed completely. I witnessed my father-in-law voraciously devouring Mahiru's underwear from the washing machine. But I didn't want to see my mother sad. Since that day, Mahiru distanced herself 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 sneak away to a friend's house, her cunning and lewd father-in-law intervened.
