When I opened my eyes, I found myself in a crate about to be sold as a slave in an auction. It was going well when the novel's male lead burst in and saved me, but all of a sudden, this man asked me to marry him. "" Please be my wife and show this empire your worst behaviour, so wicked that no one would dare to approach me when they see you."" "" What's in it for me?"" "" I'll give you 10 billion."" What the F..X..? Welcome, dear customer! I would gladly uphold the 'crazy bitch' reputation to drive away those stalker fans just to live a comfortable life. However- "" I can't imagine my life without you now."" Seems like I somehow failed to protect the male lead, and instead acquired him for myself! Will acting as a villainess with all my might bring me money, power, fame, and even love?

"Now that we have no ill feelings towards each other, let's live our separate lives well and never see each other again." It was the start of a possession that began with a typical regretful family drama. After cutting ties with a family that doesn't get along with each other, I thought a peaceful unemployed life was waiting for me. However... For some reason, men who had no interest in me before the possession started creeping in. "I have something I like." "What is it?" "It's you, Lora." The slave who I brought because I felt sorry for him getting beat up now confessed. "Why doesn't Laura take care of herself? I'll take care of her from now on." The condition of the butler, who is of mixed race, became strange. "Lora, will you marry me?" The Grand Duke, who used to threaten me, proposed. "Haa, this sweet smell... you're the first one to drive me this crazy." This crazy man seems even crazier. ...I wish they'd all just disappear.

I possessed an extra character who is a villainess in a novel. I tried to live a quiet life without getting involved with the main character. “If you run away again, I’ll tie you up and take you to the palace.” The second prince, who only looked at the original heroine, is obsessed with me. “I didn’t do it for you, so don’t get me wrong.” My self-proclaimed rival seems to have a crush on me. “Ahh! She’s so beautiful!” “If only I had been hit by her magic once!” Suddenly, there is a fan club. “Come, let us all pray reverently while looking at the picture of the noble Yerine.” My favorite heroine became the president of the fan club. …Am I really the villainess?
