The Archduke's Fabulous Fake Marriage

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 until 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 behavior, 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... 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?
