Aria, a werewolf girl raised in a human rescue organization, was taken in by the Northern Jin Peak family. The family did not take her in out of familial affection; they wanted her to replace their beloved adopted daughter Selene and marry Cassian, the heir of the Frost Court, who was rumored to be disabled in his legs and had already fallen from power. Aria saw through the deal but chose to play along: she needed the engagement to enter high-society werewolf circles and investigate the truth behind her biological mother's confiscated inheritance; Cassian needed an ally not controlled by the family to expose a long-hidden traitor.
A return feast, lineage tests, family rituals, and commercial sieges followed one after another. On the surface, Aria appeared to be a powerless bride with no spiritual abilities, but in reality, she mastered top-tier networking technology and harbored the dormant blood of the Dark Moon King. She and Cassian, who was also pretending to be disabled, tested and used each other, yet through repeated life-and-death rescues, they developed true trust. Eventually, during the ruler’s birthday banquet, they both revealed their hidden cards, exposed the insider colluding with the Crimson Consortium, reclaimed their usurped identities, properties, and family power, and turned the marriage contract that was initially just written on paper into a real choice.
