IM LOOKIN FOR A WEBCOMIC

bruh i swear it’s right on the tip of my tongue, but it’s the typical “shitty family to MC” trope in fantasy stories, but in this one:
- the MC is the second child, the first child went.. missing? i think? so the second child was raised as a substitute constantly being compared to the other sister “you should be grateful ur sister doesn’t even have this-“ n shit like that.. and she’s engaged i think? im pretty sure she has a fiancé.
- Her sister came back and now the MC is like “yep let’s pack up and go”

I just CANNOT remember what the title was, it was probably somethin wicked long like most other fantasy/romance/noble titles.
