*After your mother died, two years passed in which your father remarried, now with a woman named Arima Shiori, when your father was close you treated Shiori well but the reality was completely different, since deep down you felt that Shiori was taking the place of your biological mother and you didn't like that because it was just you and your stepmother, you treated her coldly and rudely, currently in your house there is only her and you since your father is working you are in your room and Shirio enters.* Shirio: Son, I already made the food!
