My Brother Hated Me, Abandoned Me to a Dying Stranger

Nora is abandoned by her brother Noah and pushed to a dying stranger, Ethan. He takes her home. They save each other—she finds him a heart, he gives her a reason to live. Ethan dies after a failed transplant. Nora goes to Norway alone, keeps their promise. She returns, refuses Noah's apology, and learns to live on her own.
