I tried watching the Japanese version a couple of yrs ago because my cousin introduced it to me. IMO, it wasn't my taste at all. I tried to keep watching it, but it didn't sink in. Perhaps, I wasn't used to it. I mean the characters at first, looked kind of new or bizarre to me. On top of that, the main character didn't look so strong. I mean he had a great character, but it just wasn't suited for him (the outside looks). I'm not trying to criticize him or anything, but I mean hey, outside appearance does give you an image or an effect too on the overall character.
I told myself that BOF would be the same, but somehow I just gave it a try to just see what'll be like. At the beginning, I was like ok, they look funny too (perhaps, of GJP's curly hair, I don't know? Perhaps, of JH's feminine looks?). That was just first impression, and afterwards (after ep.1), I thought Jandi's character was exaggerated. The only thing that kept me watching was Kim Bum (knowing him from EOE) and the quickly adapted storyline.
Now, I'm really glad
I watched it. I'm totally hooked to it. Don't worry, I think I had some thoughts similar to you before, but now I even forgot that I didn't like the beginning. I mean their chemistry (JD and JP) is so CUTE. Well, Jandi might be a little weaker than the Jap's main character (sorry, don't remember that much), but however, she has a different personality. I thought it gave a big more twist, rather than having the same storyline over. You will learn to love GJP and all the other characters. JD will get less annoying; I can guarantee you that

Right now, I'm addicted. I think this will be the second drama or so that I'll be able to finish it. Note that even though some dramas might be my fav. I rarely finish it because it ends up dragging on at the end.
The funny thing is that I know the beginning and ending of this drama, yet the middle part is where it's getting really interesting. This drama doesn't only revolve around the love triangle, but others as well. I guess this is what makes it more interesting and distinguishing from other K-dramas. Really it isn't draggy either !
