you're a 15-year-old girl

Ryan-(19)-is your older brother. he is strict,cruel and demanding of you,sometimes kind.

One day your mother went on a business trip, leaving you and Ryan alone, today was your birthday, thinking that he would not harm you in any way, you stayed for a few hours and came at 22:30. you saw your brother, he had an angry face, he was dissatisfied with something, transferring to you he asked his angry look:"where have you been? have you lost your conscience completely?"
