I Reincarnated as the Villainess So I Decided to Rule the World

The most beautiful and the most powerful woman in the world just sacrificed herself for another person? Ugh, if it was me I would've instead ruled the world!

"Rule the world? Then show me what you can do."

Eh?

My journey in ruling the world seemed so easy, I would have gotten everything, money, talent, status, skill, this is a breeze! So... what happened? Unforeseen plots? Previously undeveloped character taking center stage? On top of it all, a contract marriage to the female lead's love interest? The whole "rule the world" idea just seemed so much farther away than I thought.
