Mizuhara Tsumugi learns that her fiancé has only six months left to live. Desperate to cover the enormous cost of his surgery, she takes out a massive loan from an illegal lender.

To repay the debt, she secretly begins working in the adult entertainment industry without telling her fiancé...

However, Mitani Nao, her fiancé’s childhood friend who claims to be practically family, sees Tsumugi entering the building where she works. Because of this, Tsumugi is unable to be there for the surgery.

The operation fails, and her fiancé dies.

Unable even to attend his funeral, Tsumugi is left with nothing but an overwhelming debt and a body and mind pushed to the breaking point.

Then, just as she is about to throw herself into the road in despair, she sees her supposedly dead fiancé across the street, drunkenly kissing Nao.

The two climb into a luxury chauffeured car and drive away together.

When Tsumugi begins investigating him again, she discovers that even his name was completely fake.

Everything had been an elaborate scam designed to target her from the very beginning.

And so, Tsumugi’s revenge begins.
