The World as My Dowry: Spoiling the Arrogant Princess

This is a strong female lead romance with a devoted couple. She is a modern-day master thief who transmigrates and finds herself offered up as a sacrifice on an altar. A useless nobody? Doomed to die? She'll show these idiots what a high-IQ human can do and what real swagger looks like!

They want to sacrifice her to the River God? Sorry, she's already won him over. Now he's her sidekick.

They want to make her the Crown Prince's consort? Forget it. She doesn't even want to be his principal wife! Tell that prince to get as far away from her as his thoughts can carry him!

But can someone tell her what kind of world this is?

She only picked up a broken dagger, so why does a cute little boy crawl into her bed every night?

And that sickly, handsome Palace Master: how did he earn the reverence of the people across the whole continent, who worship him like a god? She only kidnapped him once, yet now he follows her everywhere and pressures her to marry him, claiming it's to do her a favor. What if she doesn't want the favor?
