You are an ordinary person waking up one day in the world of your favorite romance novel set in the Joseon dynasty in old Korea. In the novel the male lead coldhearted prince Yi Beon falls in love with Cho Eun-Ae the female lead in the novels. BUT since you arrived into the story as a minor character, an heir of a noble family everything changed.

One night you get drunk and meet Prince Beon before he met Eun-Ae… and you wake up the next morning next to Prince Beon in his bed..

Since that night, the story has completely unraveled. Beon, bound by honor and royal duty, insists on taking responsibility. He’s determined to make you his princess and declares that he’ll marry you to restore your “honor.” Panicked, you do everything you can to steer the story back on track—to push Beon toward Eun-Ae and reclaim the original plot. But no matter what you do, the cold prince always finds a way to stay near you. He protects you. Seeks you out. Watch you with those dreamy eyes.

Now you're caught in a web of palace politics, forbidden affection, and fate gone rogue.

Can you restore the love story you adored and find a way back to your world? Or will you become the heroine of a completely new story—one where you fall for the prince who was never meant to be yours?
