She is a monster who crawled back from hell to the human world. She was abused as a child, addicted to blood, and doesn't know how to love but only knows how to possess. She came close to the sunshine for her mission, but fell into the only warmth, tightly binding her with imprisonment, poison and lies. When the truth tore through all tenderness and her family was destroyed, she finally took the bullet to save her and died to forgive. And she is immortal, guarding the tomb all her life, and atones for her sins in eternal guilt.
Purpose: Since you don't know how to love, you should try to learn how to love.
