The premise of Boys Over Flowers has gained considerable popularity, probably due to the international success of its many adaptations. As such, this has lead to the production of several unlicensed and/or loosely-based versions. Siapa Takut Jatuh Cinta (2002, 2017), Meteor Shower (2009), Boys Before Friends (2013), and Kaisi Yeh Yaariaan (2014) are the best known examples.
Hana Yori Dango Final (2008): a film conclusion to Hana Yori Dango. The film premiered on June 28, 2008. It earned approximately 7.75 billion yen (US$83.5 million) at the Japanese box office. Inoue and Matsumoto again starred as Tsukushi and Tsukasa in the film.
Meteor Garden (2001): the series was the first television drama adaptation of Boys Over Flowers. The drama propelled its five leads into super stardom, compelling the four male leads to form the idol band, F4.Meteor Garden was a huge success throughout Asia.
Meteor Rain (2001): a spin-off to Meteor Garden. Each episode of the series follows a different F4 member, except Vic Chou, though he does appear. It aired in late 2001, shortly after the end of Meteor Garden. Peien Chien, Aisa Senda, and Mai Sato guest starred in the series.
