She's a Fake Villain, but the Archduke Is Obsessed with Her [Novel]

"Oh my, how clumsy of me! But since the drink is the same color as the dress, no one will notice, will they?"

In front of the entire ballroom, she humiliated her rival.
Such was Selina Arsene, high society's infamous villainess.
But…
"This is an imperial order: be the villainess!"
It was all a secret plan — ordered by the Crown Prince himself!
Having fallen for a poor baron's daughter, the Crown Prince made Selina an unbelievable offer: play the villainess, and help him win his true love.
Selina thought it would only last until the lovers reached their happy ending.
But suddenly…
"Does a lady like that deserve a place in our society?"
"She grows more insolent by the day… I want to break off the engagement!"
The act became a bitter reality.
Cast out of society, Selina was about to lose her fiancé as well!
And in the midst of her crisis, the Empire's war hero, Grand Duke Xenos Eustia, reached out his hand.
"You could have just said you were with me. You suffered for nothing."
"Pardon?"
"As soon as your engagement is broken off… marry me."
"What?!"
His red eyes stay fixed on her with unsettling intensity — and the mysterious Grand Duke's obsession is no passing whim…
