As a big fan of Hana Yori Dango/original manga/ i watched all of the adaptations and this korean version is a pretty good one. When it first aired i was still a kid who was first introduced to romance dramas. So i remember i was really digging it at that time. Since i'm a big fan of the manga i have nothing bad to say about the story. You really gotta see this drama.
Story: The story may seem cliche for others, but note that the manga is from the 90's and mangas from those old times were mainly like that. Rich chaebol guy and poor girl etc etc.. Old but gold!!!
Acting: I personally don't enjoy the performances of the actors in this drama. No offense i love the actors. But i think i would've enjoyed more if the female lead was a different actress.
I personally enjoy other adaptations like Hana yori dango (japanese), and Meteor garden (Taiwanese) more than this
