I will no longer transfer privileges to anyone

After being reborn as a poor girl, I take the elite academy spot my sweet-faced sister has always wanted. She keeps sabotaging me and taking every cent I make, but the wealthy classmates who once ignored me start standing by my side—the school bully and the campus beauty even give me a house and money. I cut ties with my draining family, ace the college entrance exam, and rise to build my own fortune, while my cruel sister and partial mother end up with a tragic fate.
