The Villain’s Contract Lover Wants to Break Up

I reincarnated as a supporting character who gets tricked into marrying the villain who promises to pay off her debt, only to die. The debt is already mountainous! At this rate, I will die just like in the original story! “Sir Isaac. Since you are my aide, you will follow everything I say, right?” “Yes, since you hired me as your aide, master.” “Then date me!” If I have a man, even the villain won’t be able to approach me! I proposed a contract relationship to my aide, thinking this would break my death flag. In reality, this man was the villain, and I never imagined that by pretending to be lovers, we would end up as the nation’s couple after he discovered my weakness.
