Hana Yori Dango
This is the story which introduced me to the manga world. I probably re-read most of the chapters more than once. I thought that at some times, the plot was stuck in a loop endlessly repeating itself but I loved every part of it down to the last page. I wanted a spectacular ending and Rui to be happy (with Shizuka) but still this is a cult manga for me (perhaps it is one-of-a-kind manga because I doubt that there is or will be anything which is even remotely similar to it).

This is a wonderful story with a very smart artwork, and a clear point of view. The author was able to shed the light on the plight of abused kids and pull us into their lives as they struggle to find hope and stand on their own feet. Absolutely brilliant. I strongly recommend that you read it. Trust me, you don't want to miss out on it.
