I am looking for a manhwa? Or it could be a manga about a girl who starts to live with her dad. I don’t remember the circumstances, but he is a doctor that is pretty standoffish, and initially doesn’t know how to raise his daughter but grows to love her and spoil her and slowly starts to change. I remember that her dad and grandma were really rich and the grandma was the head of some like fashion corporation.
The little girl was having some trouble in school with the boy she liked, and a old best friend I think. She also made a new friend who became obsessed with her dad because of how gorgeous he was...
