Ore Wa Homo Janai~!!
Hana Kimi is my favorite Japanese dorama, a live version of the anime. This was filmed in 2007 and has never been equaled. I think it is funnier and better than Hana Yori Dango. There are Korean (To The Beautiful You, which I also like and still have the OST in my iPod) and Taiwanese (never saw and liked Chinese language dramedies) versions. It has a gender bending theme a la Shakespeare's Twelfth Night and As You Like it but with the Japanese style silliness. I watched this series in 2010 and watching it again on Netflix. I still love it specially Nakatsu.
Nakatsu thought he was gay because he felt a spark and is attracted to the girl pretending to be a boy. I believe he set the trend in second lead syndrome in dramaland. I love the first couple, though, and the first series I've seen with Oguri Shun. He is also in Hana Yori Dango and numerous movies. He has a new dorama currently streaming on Netflix, Romantics Anonymous. I have seen probably half of all his TV series and movies. One of my favorites is live action movie, Lupin the Third.
The lead female enrolled in an all boys high school where intelligence and wealth are not necessary. The boys just have to be ikemen and apparently weird. Word got out that there is a girl in the school and the boys set up tests to determine who is female among the students. The tests were weird but hilarious.
Highly recommended for Japanese dorama fans.
