Hanazakari no Kimitachi e, by Nakajo Hisaya, is a manga series about a girl Ashiya Mizuki who dresses up as a boy to attend a all-boys school in Japan. She lives in California but speaks Japanese because both her parents are Japanese. She saw a picture of a Japanese boy, Sano Izumi, high-jumping and was determined to go to Japan to meet him. That is the reason she goes to Oosaka Academy. On her first day, she bumps into Sano in the hallway and becomes his roommate. But soon, Sano accidentally discovers that Mizuki is a girl. He didn't tell anyone about it, not even Mizuki, and kept the secret. As the year goes on, Mizuki becomes closer to Sano and realizes that she loves him. Sano, on the other hand, changes a lot as time goes on, all because of Mizuki. HanaKimi is a great manga series with a great storyline, not to mention really hot guys ^_^

The manga has a total of 17 volumes up until now (I don't know if that's the end). I have volume 1 and chapters 28-29 (part of vol 6) scanlations. I'm thinking about doing my own HanaKimi scanlations... so keep tuned!!
