I was reluctant to start watching this drama only because I, personally, am not a fan of school related dramas. However, after seeing a few hundred gifs of Park Heung Soo (Kim Woo Bin) & Go Nam Soon (Lee Jong Suk) together, and because they both happened to be two of my favorite actors, I decided to give it a try. After the first episode I was sincerely glad that I had. However, one of the only reasons that I finished the drama was the bromance, and man, the bromance is strong with this one. Granted the story line was actually pretty good, and every character played an important part in making this series what it was (an exploration into how people affect each other's lives and how important friendships are in shaping the lives of young adults and their futures). The drama did drag on a bit through the second half, but it never lots it's original purpose and that's what kept me interested. Each character had their own story to tell, and each actor did an amazing job telling that story. Especially the two lead teachers, who had an amazing chemistry that had nothing to do with romance. The lack of romance is definitely one of it's strengths. By not adding romance it allowed the drama to reach another level of friendship that isn't typically seen in this genre. Which brings me back to Heung Soo and Nam Soon, the two best reasons to watch this drama. Their bromance kept me going, making me laugh, cry, and throw a tantrum when things didn't go right. I can't remember ever seeing such an amazing friendship, and it's really what kept me coming back for more. Overall, I can't find many reasons not to watch this drama (well maybe the ridiculous reasons they concoct to attempt to expel students ever other day). If you are reluctant to watch it as I was, don't be. It's a great watch, and definitely made me appreciate the friends I have.
