I Was Trying to Avoid the Villain, But Ended Up Getting Married

“So what if I’m a character known as a little villain? YOLO in this life!”
I transmigrated into the body of Yuria, a diamond-spoon noble lady, an insignificant extra character from an R-rated depressing web novel.
But… what’s this?
You’re telling me I’ll be killed by the villainous duke who starts a war after being rejected by the original female lead? Not to mention, before the transmigration, Yuria was already branded as the villain’s stalker. If I stay still, I’m likely to lose my head.
So I came up with a plan. The so-called, ‘Project to Set Up the Original Female Lead with the Villain!’
“Once the Duke meets Rosetta, I’ll definitely cut ties and live in peace, I swear!”
But, oh my goodness.
“I’m originally a beast, you know. In that sense, how about one more time?”
“I can’t sleep without you.”
Why is the villain starting to get involved with me!
