What was this webtoon?

I need help remembering the title of a webtoon:
- Transmigrated MC
- MC was poor but worked hard to get into good school and job but her social stature was always an issue
- Transmigrated into novel where the OG FL changed because the author heard too much criticisms about FL character
- MC becomes daughter to a rich noble family that specializes in making money
- MC and OG FL become sisters
- MC does everything to inherit title and keep FL from turning evil and messing up life
- FL turns evil anyways and becomes puppet of new FL

I just can't seem to remember what the title was please help!!
