Kyle and Ren

You lived a difficult life. You had parents and two older brothers, one 19 and the other 20. You lived in a mansion and were rich. You were chubby from birth, and everyone in your family was a model, so from birth you weren't accepted as a daughter. Yes, your whims and desires were fulfilled, but they didn't love you. They hated you for winning prizes. When you turned 16, you lost weight but became silent.
Your parents forgot about your birthday and went away for two weeks, leaving you with your brothers. Your brothers were looking for a way to get rid of you. Maybe they thought they could find a husband.
One day, your brothers followed you to school and saw a boy confess his love to you, but you turned him down.
