Story: This was one of my first Korean dramas I watched and it was veryyyy new and different to classic TV shows I watched. Four really good looking guys... and a girl. It is an interesting story line with lots of good scenes. However I do feel it drags a bit some places. It is also quiet back and forth, I like you, I don't like you etc. But it still kept me watching and interested right up til the ending. Acting/Cast: It has two of my favourite Korean people in it. Lee Min Ho and Kim Hyun Joong. Lee Min Ho was pretty good of an actor, I just didn't feel he had much chemistry with the female lead Koo Hye Sun... unfortunately. Kim Hyun Joong, although he is one of my favourite people... he can't act that well... and it is kinda funny watching him act. He is pretty much just some great eye candy for this drama, along with the other 3 members of F4. Back to the female lead... she was annoying... and reminded me of a child. If the female lead was different perhaps the drama would have been even greater. But I guess that is what the main female character is supposed to be like from the manga and anime. But they didn't annoy me as much as her in this drama. Music: This drama, no joke, probably has one of my most favourite OSTs. It is a very memorable one. It even has songs that have made it into my GRAND playlist. All the songs from the soundtrack are really great as they bring back memories from the drama, but not just memories, they also bring back feeeeelings from the drama. Songs that I really like from the soundtrack are: "Because I'm Stupid" by Kim Hyun Joong (Acoustic version), "Making a Lover" by SS501, "Stand by Me" by SHINee and "Lucky" by Ashily. I think what topped the drama for me was actually the music. If the soundtrack was lacking in anyway, I may not have even finished the drama. Rewatch? Yesss. Despite the annoying lead and sometimes annoying storyline, it is still a very catchy drama. I think it is the soundtrack that actually makes me go back and watch the drama over and over. Whenever I hear a song from the drama, I contemplate rewatching it. Of course I would skip slow parts and boring parts, but would still enjoy it almost as much as I did the first time watching it. Overall: It is one of the most watched Korean dramas. If you haven't seen it you are basically missing out on the drama that set standards in other Korean dramas. This could also be considered the first season of the "flower boy" dramas that are very popular for their pretty boys.
