Haha! I guess she was never ugly in the first place, but the middle sister always made her to be because the dad beat her up, so she was "ugly" just because of all her bruises. Or she's really ugly in reality but for our eyes' sake she's drawn rather decent if not pretty, some would drop the story because they can't "stand her ugliness" right?
Sometimes, I wouldn't even give chance to read a story if the art style isn't to my liking
Why guessing when their is novel? Author describes her as ugly, the artist just decided to do whatever they want. MC is not diva beauty, but she is cute to some extent.
Author: She is ugly as heck! UTTERLY FUGLY!
Artist: Shut up.
