I Woke Up as the Ugly Duckling

What good is being reborn as the duke's daughter when you're the shame of the family? While her siblings were talented and beautiful, poor Sylvia was called fat and ugly, with a rumored bad personality to boot. Acting out for her cold father's attention only got her exiled from home and made her take her own life. That was the story of the girl this Korean girl who died from a weird disease got reincarnated into. But this girl who got reincarnated as the new "Sylvia" who woke up five years before her death, could care less about the snarky opinions of others–she'll live this life her own way. In a world crawling with demons and thieves, she must use all the resources at her fingertips and prepare to survive on her own. Once she does, it's goodbye to her family and the naysayers... so why are the people who never cared about her before starting to take an interest in her?
