I can only remember a bit of it. The girl is from a rich family and something happens where someone takes their riches or something. She comes back looking beautiful and wants revenge so she inlists the help of a friend or something. They end up falling in love. I believe she has purple hair if that helps. Please help me find it.

uh maybe Silver (FUJITA Kazuko)?

Thanks! I kept thinking of this and I couldn't find it. 😁
