Reina, a female college student whose mother has remarried and has a new life with her father-in-law. Reina had come to forgive her heart for her very kind father-in-law, but one day it changed completely. I witnessed her father-in-law sneaking into her Reina's room and devouring her underwear. But I don't want to give birth to her mother's sadness. On that day, Reina keeps a distance from her father-in-law, but her grandmother gets sick and her mother goes home for a while. And her cunning and lascivious father-in-law interferes with her Reina trying to escape to her friend's house.
