The appearance of a spoiled brat in a slackened Duke’s household

Synopsis

I was transmigrated into the body of Viole Rascal,
the ill-fated supporting female character who is executed by the Emperor?!

To avoid her execution, she did everything she could to stay out of the Emperor’s path,
living as a shameless troublemaker instead.
She spent every day hopping from one casino to another, with alcohol and cigarettes never leaving her hands,
fully embracing the carefree life that suited her perfectly while desperately trying to avoid the events of the original story.

“Just one year. One year is all I need. Stay married to me for that long.”

Before she knows it, she ends up entering a contract marriage
with Narsia Kegrainer, the young Duke of House Kegrainer.

…

31. Limit drinking to no more than three times a week.
32. Do not enter entertainment venues such as casinos or racetracks.
33. Do not smoke in the bedroom.
    (No little lies like, ‘I smoked outside, the smell just didn’t come out.’)

On top of that, Narsia starts restricting Viole’s every move with a bizarre contract…

Somehow, this man doesn’t seem ordinary at all.
