The Villainess Writes A Resignation Letter

I’ve transmigrated into my favorite romance novel, which I’ve read hundreds of times while waiting for its completion. Wouldn’t it be wonderful if I transmigrated as a noble lady living a comfortable life? Unfortunately, I’ve transmigrated as the villainess who tormented the heroine mercilessly, ending up dying a horrible death as a fake saint candidate. So, unlike the original story, I quickly resign as the saint candidate and leave the temple. I then set up a home for a fortune-teller who can predict fate accurately, thanks to my memory of the author’s typos. My reputation soars as I impressively predict the future, which was initially just a means to survive. As a result, the temple that once ignored me, the first prince embroiled in the Throne of Blood War, and the next Ma-topju (the highest-ranking official) consumed by unprecedented narcissism all begin to obsess over me. To escape the most dangerous part where I’m killed off in the original work, the temple, I must enter into a contract marriage. But who should I marry to make it work? After much deliberation, embarking on a contract marriage proves to be anything but easy. How does one navigate a wise married life?
