I really went in to watch the drama with high expectations. It delivered on some fronts and failed on others. The F40 having a bromance was the main reason I was tempted to watch it. I love tales on friendship on any given day. If it were just for their friendship I would give it a full 10. The female leads of the show are the reason the rating goes down to a 6. It started out really well too with the romantic plots and there wasn't a single boring moment till midway. However, when the drama ran half its course right from then I found myself struggling to stay interested. The F40 or all the ajhussis were cool in their own way. They gave off a fresh feeling but pretty soon it became stale. The problem didn't lie within their characters- but with what they became when it came to the women they loved. Speaking of, there wasn't a single female character I found myself loving. I only liked one and the rest were annoying. The main female lead is one of the worst and inconsistent characters ever in a Korean drama. Her friend was hardly better or even Mah Ri, who was cutesy with her aegyo in the beginning and then redundant in the later half. None of the characters ever grew much. Then there was a certain sub-plot which was completely unnecessary and pointless. I felt like there was too much time devoted to senseless things than important stuff. There was a lot of potential to make this drama near to perfect. For me, this drama was like being promised a cake and only getting the cherry. It was such a disappointment. By the end, I was glad that it was over and not really caring about what happened to the characters. Hence, what we are left with is a one-time watch.
