The Korean series from 2009, "Boys Over Flowers," was my first introduction to this story. I loved it so much that I decided to also view the Japanese version that had come out a few years earlier. Now, I'm not sure which version is my favorite. Although the stories are virtually identical, there are enough differences to make this a worthy viewing even if one is already familiar with the basic plot line.
THe Korean version is more glamorous, with beautiful sets, exotic locales, incredible fashion on display, and the actors are more physically beautiful, which enhances their aura as a group of super-cool, privileged young men. But the Japanese version stands out because the heroine and main rival to the primary love interest are much more demonstrative and direct with their feelings. We feel the heartache and confusion all the characters feel as they deal with this love triangle. And, without extended back stories for the supporting characters, there's more time to devote to developing the relationship between the main characters. My advice, see both versions.
