MC got murdered by her family, go back in time with the power of The World and thinks she's the best villainess around. (Like you went back in time, you just know what to do to deal with the rats, stoopid)
She kicked her family out of the house. She spent 40 chapters doing some kind of Hunter Exam for nobility or wtv.
Ah and the ML is the biggest dickhead in history.
Then she meet someone who could have been the best ML in this story but they are siblings ? And out of nowhere, she's a royalty because of her mom ?
Now she's locked inside the king castle because her new siblings don’t like her ? And the king/emperor/i forgot wants to do wtv he wants to do ?
Ah and people have the same kind of power than her, like ML can TP, i think ?
Yeah that’s pretty much it

Someone just spoil me all of it.
