Guys help me find a manwha please!!!

So I read this a WHILEE ago it's a pretty old manhwa, so this girl reincarnates into the body of a Duke's daughter I'm pretty sure and she's blonde, she gets selected to be a crown princess candidate and has to fight for that position as the prince has a gf and she's also selected to be a candidate and for this they have to move to the palace and the mc has a bad reputation (duhh) also the ML aka Crown prince hates the MC's dad cuz the Duke was supporting his brother who got killed as a child and the ML still remembers and hates the MC cuz of that, he's fake dating the brown haired fake ahh bih cuz she proposed the idea that she only wants power and doesn't mind being Empress in name, the ML ends up falling for the MC tho cuz duhh and I really wanna re read it even tho I remember everything from the manwha but I can't remember the nameeeeee I think the MC's name was Charlotte??? Idk
