Unfortunately, there is no English-translated novel yet. There is only a forum where a good Samaritan translates chapter spoilers into English. Based on where the manhwa ends, we are currently on Chapter 232 of 600+. You can read it here:

Here is also the original Korean source [ https://page.kakao.com/content/50746174].

I really hate her family( ˶ ❛ ꁞ ❛ ˶ ) they're all superficial. They only notice her because she's now a beauty. They didn't even defend her when she's young and being bullied by other people tsk

Her sister is nice but a softie.. And very dramatic any small thing Sylvia says to her she gets hurt and cries then the bullying fall on Sylvia and even when her sister get bullied because of her she doesn't do anything. Even if the old Sylvia did something to her but still it showed the young sister would get dramatic for anything that any bad action falls on Sylvia. Very neglectful family.. Her sister character shows she care about herself more even if there was bad treatment on Sylvia and didn't do anything but cry a river.
Seriously, they just won't stop provoking her.
