Well, a friend recommended this Drama to me and at first I wasn't so sure if I'd really like this Drama, I've seen quite some school Dramas and I didn't think it would be somehow special or new. But I was wrong, after the very first minutes of it, I was totally packed! The characters and their development in the story is very well, the characters are really authentic and the cast also is very nicely chosen! It also is a very emotional Drama, I've probably cried half of the time, not just because of sad moments, also because of happy moments.I really loved the main characters. But what I disliked again is the end. It - again - feels like it just (and I hope that's not counted as a spoiler) stopped in the middle of the story, and many "side storys" haven't even been mentioned anymore... But overall I really loved this Drama. I thought of giving it a 9/10 because of it's end, but it's just been to awesome, so I simply couldn't do that! I would really, really recommend this Drama to everyone, who likes a dramatical plot with sometimes very surprising changes! So... to go into more detail (I'll try to not write any spoilers! I hope none will sneek in!) To the story: Most school dramas are happy and fluffy with sort-of dramatical scenes, but.... not really realistic. This one on the other hand was very, very realistic. It was sort of dark, there was violence, drama, stress, it just seemed like that's how school in S. Korea could really be! And from what I know, it's also meant to be realistic. Another thibg I liked about the story: other dramas, mostly school dramas are about romance, but this isn't, there may be a hint of possible romance but in the end there really isn't! Also, I think it's hard to really say this and that person are the main characters! It was all about the whole class and also about the teachers, of course the listed main characters had sort of more screentime, but in the end everyone mattered in some way! Even though I liked that it was so realistic, also about violence, not hiding anything, seeing the characters getting beaten up was very, very gard to watch! I also liked, that many characters had their own back-story but it was sad, that not everything was cleared up in the end, actually many things were left open which I always hate while seeing Dramas, and I will never get used to it! Now to the acting/cast: I really, really loved the cast, actually I found 2 actors I didn't know/haven't paid much attention to before, which I now really look up to! I don't know much about acting, and when I get into a story I don't really pay attention to that at all, and since I was really absorbed by the story, I can't say if the acting really was good or not but for me it simply was. The actors seemed to have very good chemistry which you also felt while watching, what they did just seemed realistic and not acted, sure there may be some scenes, but honestly I can't remember any... To the Music: I wouldn't say it was overly awesome, but I liked it and it was fitting, so I'm satisfied with that. I probably won't rewatch it that soon, but that's rather because I can't watch something I just watched after a short time again, also there are just too many other Dramas to watch. Well, overall I can just say that I really, really love this drama. It is by far one of the best dramas I've watched till now.
