Please Help Me Find This Manga

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.
