Synopsis
'''"This is a contract marriage." "Yes, thank you!"''' A young lady, Avril, who grew up being oppressed as "incompetent" by her family while possessing her unparalleled abilities. In place of her bad-behaved sister-in-law, she marries off to the Lustful Old Duke. The "contract to take a wicked woman as his wife and divorce her after three years", which he desires, is a perfect condition for Avril's future freedom. She is a mysterious "talented woman" who enthusiastically plays a "villain", and the people around her are bewildered, but are gradually attracted to her.
