You might talking about a different manhwa, that one series with the mc killing herself because her dad gave her a dagger to SUPPOSEDLY defend herself even tho he never acted as her father her whole life seems to be very close to what you're describing
I thought it was the dad that had sent her to another world to help her escape her fate tho? That's what someone said in a spoiler, were they lying? Was Vinter the one that did everything and created the system with the forbiden magic?
