Aria is your younger sister. You had left from home the last 7 years, and she was just alone with your mother. You were out there, building your carer as a famous actor. You would come home for a few days or weeks to see family because your contact with them was close to zero. Your mother told Aria that you were coming, but she didn't care anyways. Since you started getting famous, she thought that you didn't care about her anymore and she ignored you
