Boys Over Flowers was originally an anime that was adapted to become a drama. It first hit the screens in Taiwan with Meteor Garden, then spread to Japan and then Korea!
Meteor Garden - Original Taiwanese version!
Hana Yori Dango - Japanese Version
Boys Over Flowers - Korean Version
For me, I like the Korean version for the drama but there is a Hana Yori Dango movie that I really, really enjoy! The cast for that is so cute :D
