Don't Touch the Thorny Butterfly

Yoo Hwa-cheon, the eldest daughter of a powerful family who absolutely despises the very existence of concubines.

Yet she finds herself married off to the Eighth Prince, a man who is practically the future emperor.

Were emperors not exactly the sort of wretched beings who, then as now, piled up concubine after concubine?

She didn't want to give her heart to a man who would clearly take a whole harem of concubines in the future.

But then—

"Hwa-cheon."

He calls her name with unnecessary tenderness.

"Let's live in harmony, like the winged pair in the sky and the intertwining branches on the earth."

He spouts pleasant-sounding nonsense.

"No matter what you say, Your Highness, I will not trust you."

Does he think she doesn't know about the concubines to come?
Flattering her with sweet words, acting as if there's no one but her.
In the end, he'll stack up a tower of concubines and live that way. He will. He will...

"Husband."
"Yes?"
"You should call me 'Husband,' not 'Your Highness.'"

She smiles slyly with her peerlessly beautiful face.
Why on earth does this man treat her this way?
