Beware Of The Villainess!

I became an antagonist in a novel! But it didn’t matter because I was the duke’s daughter, a wealthy man. This is clearly a great opportunity to enjoy life. In the novel, the male lead is the Prince, also my fiancé, who is deceitful and dishonest. He even cuddled another lady right in front of me. However, I didn’t cry anyway! That philanderer is not worthmy tear. Instead, I shouted “You are rubbish, your Majesty ” The FL is such a girl crush who will completely amend the planned story!?
