It matches the first part
YESS !!! That first scene is the one I was searching for.
Maybe I mixed up the later part but that's the one thank you !!!!
This will be a very sloppy description of the webtoon I'm searching. Because in afraid to mix up the story.
So it's about a family where one of the girls is being mistreated and she than is set to be burned in a place where they have always burned their "sacrifices" but she survived it without them knowing (not sure about this part, maybe she died and reincarnated?) and then she was adopted by another family where she was treated really well and she got to take her revenge. I also think they wanted to sacrifice her do that the a sister with the right eye color and right hair color gets her power ?
I'm really not sure because there was a similar story to this one do it could be that in mixing up the storylines.
But please help me find this thank you !!!
