Honestly, you guys probs see the MC’s og form as super pretty bc that’s how the artist made it out to be in the webtoon. As for how she was meant to written, realistically, she could just be your avg plain jane. Not ugly or anything, just not absolutely as drop-dead gorgeous as Libertia was.
And regardless of how you actually look, if you’ve got a less than stellar self-image, which the MC might have, that’s gonna affect how you describe yourself
