To be honest, I wasn't intending on reviewing this drama because I know it will have a million reviews since this show was THAT amazing. This review is purely based on School 2015, not any other adaption, I've only seen School 2015. Prewritten as the story went along. -- Story: So, this is a story that has been done before well.. in a way. The school element has been done, which isn't a bad thing when you add new elements. Eun Bi is a twin to Eun Byul and there is a bunch of mysteries surrounding their lives as they start to become one. ( Mini plot summary sorry :0) But yeah, the fact that I haven't seen something like this makes me even more excited to watch. Although I don't particularly like suspense, once I watch I get so captivated into the story that I don't even mind my interests because It is indeed interesting to the VERY end. OST/Music: Amazing. I even added some of the music to my iphone, I love when I can find good songs out of dramas that fit the mood perfectly. Trust me, the music doesn't mess up the vibe of the story or scenes. Characters: Kim so hyun.. wow. She has made me a serious fan, I seriously enjoy her acting! While watching this I didn't realize how young she was, but that doesn't even matter because she has the maturity and the skills to act the part she needs to, I look forward to more of her work. I also love both her characters Eun Bi and Eun Byul, there is more to their story that meets the eye and I enjoyed trying to figure it out myself and finding the answers to my questions. I also loved the male leads. I didn't have second male syndrome or any of that, I couldn't choose any shipping to be honest.( Edit, after episode 14 had second male syndrome)( Edit 2: Then.. when i got to episode 15 i Couldnt choose anymore xD) That's how perfect both the characters were to me. I was also happy when there wasn't even any romance in certain scenes because the chemistry in this drama is on point, ( this comment says something because I normally can't watch a drama that doesn't have alot of romance). I do wish that there were parrings.. you will understand when you watch. Overall: Should you watch? yes. Yes. omg I can't get enough of how much I loved this drama, you even have people reviewing the drama before It was even over that shows that this drama was really good and anyone should be able to enjoy It doesn't have alot of drama but it does have important life messages with a bit of romance and more drama to top it off to make it interesting. You wont regret watching the drama, it may make you pull your hair out and the ending may not be what everyone was expecting, but overall i can say its a worth watching drama. ~Ari
