Still on the hunt for this manwha ಥ‿ಥ

I'm looking for a isekai manwha, where the FL (blonde) (she wore a cloak and hood because of her scars) on her past life defeated the devil(?) but was killed because they have no use of her (ig? I forgot the reason). Before she died, her dragon (mentor? Teacher???) gave her one last wish, and that is going back to the past, thus found out that her father was the emperor that was looking for her since her disappearance. ( She has twin older brothers, one was mean at first and called her ugly etc. the other one was nice to her) ( The one that called her ugly has depression due to his first love death and he also killed himself in the 1st life)




I also remember specifically, where the FL's adopted family sold some her hair, thus having short hair, but coincidentally found by her real family to turn into a wig for her
