I'm looking for a webtoon, where the main character (mc) dies and is sent into the world of a novel, where she wakes up as a child. She knows she is the villain and wishes to change her fate.
She becomes close friends with the female lead and the male lead is brought to her home (I honestly cannot remember how he got there.) I do remember that the original female lead's (og fl's) older brother comes back into town from school and the ml becomes jealous, because the og fl wants the mc and her brother to marry and he wants to be with the mc.
Another thing I remember is a scene where they are at a festival and get separated from everyone else, then attacked by a demon; she some how bonds with said demon and it becomes a cute squirrel.
I can't remember the name or if this was just some random fever dream I have had. Please help!
