Reborn as a Wealthy Villain Who Dotes on His Wife

To avoid marrying the man who was once all-powerful but is now unable to walk and has lost his memory, the older sister and their mother plot to make the younger sister sleep with him.

By sheer coincidence, Xia Yunxi transmigrates into the younger sister’s body. Before she can figure out what’s going on, she somehow ends up registering her marriage to the man?

Once she sorts things out, she realizes she’s transmigrated into a book, and she’s only a minor female supporting character? Her husband in name is a minor male supporting character, and they’re both major villains!? None of that matters. What matters is that the original heroine can foresee the male lead’s future! She’s already set her sights on the villains! What should they do? What should they do? Help, urgently!
