After their parents died in an accident, sisters Esley and Liana were left with an enormous debt.

Esley, the elder sister, despite being called a "villainess," curried favor with a wealthy old count and raised her younger sister, Liana.

That elder sister fell in love.

Wanting to bring happiness to her sister, who had endured so much hardship, Liana decided to take her sister's place and shoulder all the past ill repute.

A duke with a hidden agenda proposed a contract marriage to that "villainess."

Liana accepted it for her sister's happiness, but a year later, she was divorced.

But a year later.

The duke who was supposed to have divorced her, was searching for Liana.
