I am a good-for-nothing orphan girl who was thrown away by my family to the werewolf territory to be married off. My husband is a ruthless pure-blood wolf king. He only married me to avenge my sister's betrayal. For three years I was despised by the entire pack, and he looked on with cold eyes. Not long after I coughed up blood and was diagnosed with silver poisoning, I burned all the wedding rings he gave me and crushed the moonstone in front of him, which was the only way to relieve the pain. Later, on the day I fell in the snow, the wolf king in the entire territory went crazy. He looked through all the ancient books with red eyes, but only found the note I left: "The substitute contract has expired and will never be resurrected."
