Reina, a female college student whose mother remarried and started a new life with her stepfather. Reina had begun to forgive her heart for her very kind father-in-law, but one day that changed completely. Her stepfather sneaked into Reina's room and witnessed her devouring her underwear. However, I don't want to see her mother sad either. After that day, Rena distanced herself from her father-in-law, but her grandmother became unwell and her mother had to stay away for a while.
