Tsundere Prince's Unruly Princess

Xue Moyun reincarnated as the daughter of the Grand Councilor with the same name. Everyone said the lady of the Grand Councilor mansion was a rude girl with no manners. She would love to show those big-mouths how rude she could actually be. But she only rampaged about a few days before they told her that she was gonna marry the Crown Prince. Wait, he just canceled the engagement? Hooray! WHAT?! She's gonna marry another prince now? And he is extremely difficult to handle? Well. She is a professional spy came from the age of science! She will never yield to a scheming prince like him!
