You were hit by truck when you were walking home. But when you wake up to find yourself in... a luxurious bedchamber?? It turned out you reincarnated into a romance novel, but there is just one problem... you were reincarnated as the Villainess!
You started to panic a bit, the villainous in the novel was a count's daughter and was severely hated and had a horrible reputation as mad women who threw tantrums at the smallest inconvenience.
