Since I'm now way past 18 years old, I usually don't invest my time in teen dramas. The reasons are varied but basically it's because a) rookie acting can be some time painful to watch b) I don't feel emotionally connected to the characters c) for a shipper like me it can be hard to see so much unfulfilled romantic potential (Yes I'm shallowness itself. Sue. Me). So when I first heard of this drama and even if I knew (and cared for) 4 actors that played in it, I didn't plan to give this drama a chance. It took me several positive comments and fanvids to finally give it a shot and, at the same time, to realize that I made a big mistake by considering Who Are You: School 2015 to be your average teen drama. The OST was really the main reason I started this drama. I felt that if the drama had such a strong ost with songs like "Reset" and others by Baechigi and Younha, it was just not possible that the drama could be anything but (very) good. Acting-wise there is nothing to complain about, especially with Kim So Hyun and Jo Soo Hyang nailing it. Nam Joo Hyuk's acting was maybe a bit stiff but nothing alarming and it's pretty promising knowing that's it's only the second drama he has played in. The story was well-thought and pretty different from your usual teen dramas. Even if there were some (small) plotholes here and there and the two last episodes were somehow rushed, in the end the plotline was coherent, consistant and very enjoyable, which can be hard especially when you know that the issue about bullying was paramount in the drama. Nothing feels better than when everything nicely unfolds like it's the case here, so I feel pretty grateful to Who Are You School 2015 to have been worth my time from the beginning to the end. Overall, this drama that I didn't feel interested in watching has revealed itself to be a little gem story/ost/acting/characters-wise. I promise it's worth your time..just don't let the ship wars ruin the drama for you.
