That Night of Betrayal Beast's Obsession

Framed by her fiancé and stepsister, Jane accidentally trespassed into the forbidden territory of Howard, the Beast-kin ruler. After a single night, she was forced to sign a cohabitation contract. Relying on her mother's posthumous manuscript, she mounted a comeback and sought revenge. However, on a full moon night, she awakened Howard's snow leopard bestial nature and, in turn, awakened her own SSS-rank Guide bloodline. The two progressed from a contractual partnership to a soul-bound connection, joining forces to crush conspiracies and quell rebellions. Ultimately, they became interspecies mates, ruling the empire together.
