Crimson Vows, Reborn Souls.

A fallen emperor dies, drowning completely in regret for destroying the only woman he ever loved, his first wife, Ruoyan, whose life was ruined by palace schemes and her manipulative older sister. Reborn at 18, he rejects the throne and chooses a new path: to become an honorable general strong enough to protect her and punish those who wronged her.

But Ruoyan has returned too, reborn at 17, carrying the soul of a clever sociopath who now hides behind her innocent facade. With a demon's cunning and a woman's quiet fury, she plots to dismantle her sister's life piece by piece, arranging a marriage between Ruolan and a "perfect" nobleman whose dark secret will consume her.

As the reborn 5th prince fights to redeem himself and Ruoyan's heart, she dances between sweetness and danger, testing him while manipulating fate itself. Together, they become a beautiful and terrifying force, rewriting destiny, exposing hidden monsters, and falling into a dark, intoxicating love neither death nor betrayal could destroy.
