My vampire princess wants to repay a debt of gratitude.

In a world where vampires are feared and revered, Lin Mo's peaceful life is turned upside down by the arrival of Ye Zimo, a vampire heiress. Unfazed by the traditional vulnerabilities of her kind, Ye Zimo reveals herself to be a daywalker, impervious to the sunlight that normally serves as a potent deterrent. As Lin Mo becomes increasingly fascinated by her invincibility, he begins to question the nature of her existence and the limits of being human. With Ye Zimo's cryptic words, "Unless you stop being human," Lin Mo is drawn into a world of intrigue and discovery, where the boundaries between human and vampire are blurred, and the true meaning of existence is left to be explored.
