Please Help Me Find This Manga

A classic one that the fl dies and gets reincarnated As a child but her family hates her and the ml lives with them too. And she tries to do something to him because her father told her to.
I don't remember anything about it TT but at one chapter the fl collapsed and coughed up blood and the father summoned her despite that and he really didn't give a shit.

Okay, so all I can remember of this manga are short bits, this may be a one shot.

Parts I remember:
- The main character has his name written on the school chalkboard for I think after school thing. He just thinks it is a bullying trick.
- He goes home and when he goes to sleep wakes up at school about to fall off the school's roof only to be saved by a old friend.
- He was selected to part of a afterschool program that are suppose to watch and record the spirts of the school that are baby urban legends
- They are advised to sharpen one of their nails to help them break out of any spell the spirits may catch them in
- The main character draws
- Spoilers that I remember; his spirit that he was watching and painted was a doppelganger and one of the member's died from their spirit, I think her spirit was called the red cloak.

Please, help me find this manga.

Please help me find a bright and cute manhwa that I’ve been thinking about. There’s a scene with a little blonde baby prince who’s going through a hard time because his brother treats him badly. Then there’s another kid—he’s the older brother of the female lead—with a soft silver or bluish bob haircut and bangs. Even though he’s still a kid, he becomes friends with the baby prince, and they start writing letters to each other and become pen pals. That’s all I remember, but I really hope to find it again.

Hi does anyone know the name od this manga?
The MC woke up in the past in a pool of water because the person he got reincarnated as was trying to drown himself. The MC is something like an emperor? The ML is at first some kind of advisor or something like that for the MC but in the end turns out the MC is not really an emperor he is just a decoy for the real one so that if he gets killed the true emperor is still alive. And the real emperor is the ML.
