I remember I had several volumes of this japanese manga when I was little (around 1997-1998, but I'm sure the mangas were published much earlier), but I was too young to understand it. I think it was about a daughter of a tycoon who was forced to live in poverty after her father was murdered to hide from those murderers. If you know any old manga with a plotline similar to this, please tell me, because I've been searching for it. I think the main character has blond, long hair.
