One afternoon, Lady Lumi Austin, the Duke's daughter, witnesses an affair between her fiancé, Prince Craig Barclay, and her twin sister, Marie.

Although Lumi had suspected their infidelity, witnessing it firsthand deeply shocks her, and she flees the scene.

However, someone pursues her.

It was Lawrence, her fiancé Craig's twin brother.

Lawrence is the fiancé of Lumi's twin sister, Marie.

Lawrence, too, had suspected the infidelity between his own fiancée and his twin brother.

Lawrence makes a proposition to Lumi.

"How about we give our fiancés what they deserve?"

Lumi, who lost her voice due to the shock of her mother's death, and Lawrence, scorned as the 'White Pig Prince'.

Now begins the duo's revenge-filled reversal of fortune.

※Happy Ending. A classic story of giving scummy fiancés their just deserts. Please forgive the convenient and loose plot settings.
