ang funny:  GMA 7 is airing Hana Kimi - Japanese version; while ABS-CBN 2 is airing Hana Kimi - Taiwanese version.  The latter claims it has the "original" version.

FYI, Hana Kimi, primarily known in Japan as Hanazakari no Kimitachihe (花ざかりの君たちへ, Hanazakari no Kimitachihe Lit. "For You in Full Blossom") is a shōjo manga series written by Hisaya Nakajo. The manga was serialized in Japan in Hakusensha’s Hana to Yume (Flowers and Dreams), which came out bi-weekly (5th and 20th of every month). This manga series has ended at volume 23 in August 2004 in Japan [with a special ending released December 2004, and a extra special, showing Kayashima's point of view in the story, released in 2007] The final volume is set to be released in the US as of April 2008. An artbook was released in May 2005 in addition to a character book. [http://en.wikipedia.org/wiki/Hana-Kimi]

The Taiwanese version was produced by and first aired on CTS and GTV. The show later re-broadcasted on Singapore’s Channel U as well as Hong Kong’s TVB network. Hua Yang Shao Nian Shao Nu is the second Taiwanese drama to be based on Hisaya Nakajo’s manga, Hana-Kimi. The drama features Wu Chun and Jiro Wang of Fahrenheit, and Ella Chen of S.H.E. The soundtrack was released on December 1, 2006. [http://en.wikipedia.org/wiki/Hanazakarino_Kimitachihe]

The Japanese version was produced by Fuji Television and first aired on the July 3, 2007. The drama features Shun Oguri, Maki Horikita, and Toma Ikuta. The two theme songs are Peach by Ai Otsuka and Ikenai Taiyou by Orange Range. Filming locations include the Ryutsu Keizai University. [http://en.wikipedia.org/wiki/Hanazakari_no_Kimitachi_e]

For those familiar with Jdorama,  Shun Oguri was in Hana Yori Dango. Ai Otsuka’s Planetarium was also in Hana Yori Dango’s OST.

So, with Hana Kimi, think of Meteor Garden and Hana Yori Dango — both coming from the same Japanese Manga with the Taiwanese first making it into a live drama.

My take after watching the first episodes of both versions of Hana Kimi at http://www.mysouju.com… I like the nihongo one better.  Partial lang siguro; pero, the Taiwanese version seems sooo corny and the lead girl is somewhat OA eh. Take your pick :p
