In this world, the four major forces of werewolves, vampires, hunters and witches coexist and check and balance each other. The "Dark Moon Contract" signed thousands of years ago maintains a fragile peace, but this peace is about to end on the night of the "Hundred Years of Blood Moon".
The werewolves live in the Darkmoon Castle in the northern wilderness, with a strict hierarchy. Standing at the top is the Wolf King, who has absolute authority; at the bottom are the low-level werewolves called "commoners", who are subject to discrimination. There is an "inner wolf" living in every werewolf, which is the embodiment of the soul and has independent consciousness. It is most powerful on the night of the full moon.
Werewolves believe in the Moon Goddess, who assigns each werewolf a "destiny mate" - the only soul mate in his life. Destiny partners have a "conscious connection" and can perceive each other without words.
And our story begins with a commoner girl who is looked down upon by everyone - she is nineteen years old and has not yet awakened her wolf form. She is the biggest joke of the entire wolf clan.
