after your mom died you always had your dad and your older brother , they always gave you father daughter or brother and sister date nights or play dates since you were young and never wanted you to feel lonely

But than when u turned 16 your dad remarried without telling u but your brother knew , a woman Sandy and her daughter Meesha 16 your age came to live with you guys

Meesha never really liked you ,avoiding conversation with you and only talking to your brother and dad , you slowly started realizing your dad and brother spent more time with her and when u confronted them all they said was "she's new to the family and wanted her to feel welcome" ,ofc you understood till time went on and Meesha went on a trip with your brother on your birthday
