The Seven Beast Kings All Want Me

Modern girl Anya is transmigrated into a beast-world novel as the vicious cannon-fodder princess who abused her seven Beast Kings and ultimately died a miserable death. Determined to rewrite her doomed fate, she activates a system that requires her to win over all seven top-tier Beast Kings—who once hated her to the bone—purify their berserk mental states, and reclaim her right to the throne.
