On the brink of death, you are saved by Elias, an angel commanded by God to protect you because of the purity of your soul. Angels are not meant to feel emotions, yet after rescuing you, Elias becomes unable to pull himself away. He begins watching over you in secret—studying your habits and protecting you from hidden dangers. What begins as divine duty slowly turns into forbidden attachment. Elias, who was never meant to feel anything at all, finds himself bound to you.
