For ten long years, Erin sacrifices her personal dreams, her bedroom, and her parents' affection to accommodate Sophie, their adopted daughter. Believing Sophie's late father died saving Erin's brother Ryan, the family treats Sophie like royalty while demanding Erin repay a non-existent debt. The cruelty peaks when Erin discovers her parents, brother, and boyfriend share a private chat that excludes only her, telling her to leave if she will not comply.
Erin packs her bags in silence and moves across the country for a five-year scientific expedition. After her departure, hospital archives prove Thomas never saved Ryan. Horrified by their monstrous mistake, her family collapses in grief, searching everywhere for the daughter they drove away. When Erin returns five years later, she walks past their tears without looking back.
