Hwanghu Gung Che Daesaeng

A beautiful flirt whose blatant honesty comes off as harassment, Shin Hae-seol, a college student living life to its fullest.

But somehow, she wakes up as the "Empress" in a strange place. She is required to be elegant, beautiful, graceful, and dignified as an example to the other women of the country. To make things worse, she isn't allowed to leave her husband (the emperor) who spends his days having flings with concubines. However, hope comes down from the sky in the form of a mysterious message.

"If you kill the royals, I will send you back to your original world!"
