Hana Yori Dango

A girl from a poor background attends Eitoku Gakuen and hopes to remain unnoticed during her final two years. After defending a friend from the F4, the four most influential and wealthy students at the school, she receives a symbolic "Declaration of War" from them. Rather than backing down, she becomes involved with one of the F4, Hanazawa Rui, and begins to realize there is more complexity to their lives than initially appears.
