Nuit couleur larme

Thanks to NetGalley for this arc comic book, the opinions are my own.
The cover, the premise, the art style were so amazing and got me hooked into it.
I gotta say it's soo weird, the witch girl on the cover isn't really a witch, but a young cosplayer who is kind of depressed and loves horror books, comics, and movies. Weird. I didn't understand almost anything, but it still made me read more. She summons this demon girl who grants a wish, but she doesn't know what to wish for so they become friends maybe even lovers, dunno. There's this other kid who comes to Teresa's shop who loves to read manga and the demon girl loves Japan so much for some reason. They become friends and just go to the woods and become drunk... There's also this ghost who is making people disappear and weirdly they meet her too. SPOILER turns out that little girl Matilda was the one missing, but people just forgot about her?? I didn't understand what wish did Teresa even ask for, and the end didn't feel like an end.
It was very melancholic and it felt like the one who came up with the idea was drunk too???
