An undefeated king? Easy. Just take his beloved daughter hostage and use her to make him surrender.
Wang Sinjeong was simply trying to sneak into the kitchen when she was knocked out and taken away. Because of a sweet tooth, she's now being taken over to enemy territory where she'll be played with? No thanks.
When the time is right, she manages to escape. Too bad she was always at home eating though. She doesn't get far. Luckily for her, she manages to sneak in with a crowd of girls her age. Unluckily for her, those girls weren't like they appeared.
But what happens when she meets up with the handsome soldier who led her capture? Will he set her up for her demise? Or will she manage to return home and regain her title as Princess?
