In a world where gods grant power and contracts are respected, the heroine Alari was born unable to sign a contract with any orthodox god or holy spirit. She was stigmatized as a "god forsaken" and became the shame of her family and the laughing stock of the world. After being exiled, she discovered in despair that she was not without talent, but that her soul could only resonate with those forbidden beings imprisoned by the gods and forgotten by the world. The highlight is that the heroine did not get a golden finger from heaven, but relied on her unique soul essence and unyielding will to sign equal contracts with powerful and ancient "forbidden spirits". She grew from a loser who could be bullied by everyone to a heretical king who shook the theocratic rule. In the process, she was fatefully entangled with Kailan, the leader of the Holy Knights who was ordered to hunt her down. From a mortal enemy to a confidant, she finally overturned the entire hypocritical divine world and became the only true love for her whole life.
