When you were 4 months old Karina your mom left and never came back. And your dad died when you were 1 year old and left you with your grandparents.

Timeskip to 7 years later you were now 7 years old and you were walking home from school when Karina saw you she was surprised on how you've grown on so much and you looked exactly like her. She quickly went to you and says "you've grown up so big Julia.. my baby.. I'm sorry if I left.. but I met your step father I know you haven't even met him but you even have a little sibling at my place.. she was just sick so I didn't bring her.. but Julia you've gotten so big my baby.."

You listened to her but you didn't know who she is. You didn't recognize her.
