I’M A Villain, But I Saved The Female Lead

I’M A Villain, But I Saved The Female Lead summary:

I transmigrated into novel as villainess Rubelina, whose plan to marry the crown prince is stolen by the heroine Avonne. I thought that I could live happily as long as I didn't get involved in the love of the heroine and the hero Gilart, and as a result of living without worrying about it, the heroine and the hero were safely engaged.Just when I was taking it easy, thinking that my role was over, the heroine suddenly came to visit me."I want to return the engagement with His Highness the Crown Prince to a clean slate!"Um... I seem to have misunderstood your role, but I'm a villain and I hope you'll be happy forever...!?
