Help me find these 3 mangas please

1- the first one I remember only the main protagonist. She has white hair and is an extremely funny manga. It's like reincarnation I think. She has a butler she uses as a horse to run against her father to grab some letter who is just as crazy as she is. Also white hair. I'm sorry if that's not much to go off of.

2- This is very vague, but it's definitely one where time goes back. And the protagonist is taking revenge, obviously lol, and she was pregnant before time went back. She always wondered what happened to her kids. If their souls like went to someone else. And she somehow meets the reincarnation of one of her kids who knows about her.

3- this is even more vague lol, it's another funny revenge manga. It's just because of one scene so it's imposible for me to find. Literally the protagonist opening the door to the male protagonist room, and he is extremely handsome so her heart literally drops and she has to pick it up. If you guess this one I'll be your slave I promise.
