After I Transmigrated into a Book, the Villainous Tyrant and I Swapped Souls

After dying unexpectedly from working overtime, Xu Qin'an discovers that she has transmigrated into a novel as a cannon-fodder villainess.

To survive in this world instead of meeting an early end like the original character, she accepts her fate and agrees to marry the tyrant in someone else's place.

Once she enters the palace, all she wants is to cling to the female lead of the original novel and stay alive a little longer. But after falling into the water one day, she somehow swaps souls with the villainous tyrant.

Well, now she has to worry not only about her own life, but also keep the tyrant from getting himself killed every second of the day.

So when the tyrant insults someone, she soothes them; when the tyrant causes trouble, she cleans up after him... Xu Qin'an is exhausted...

Wait, why is the tyrant looking at her more and more strangely?

This isn't how it went in the book...
