I really enjoyed this series. The acting was good, there was nice growth in the characters, the music played a key role and the story line fresh. However, I did get annoyed with the show towards the end. It is not like they killed one of the main characters or forced the OTP to breakup but it was how they dragged on and muffed up the OTP romance line that had me baffled and annoyed.
Let's face it, the bulk of the plot is the romance of the OTP. They are cute together and their dynamics are great. BUT that went on and on for 40 episodes and they don't even hold hands! Even though both are totally into each other and there is constant flirting and teasing (and no small amount of prompting by the ML). When you considered that each of them have separately told everyone who would listen that the other half of the OTP is their one and only. They even told the rival love interests so that there is absolutely no chance of a love triangle. Yet the OTP still live in this bubble where they don't seemed to believe that the other half are in love with them. OMG, are they deaf and blind? It is so obvious to everyone else that they are in love.
Fine, drag it out if you must but why when the ML finally confesses in Ep 42 (out of 44), the FL rejects him, calling it a joke. OMG! Why? She even stated again and again in other episodes that she hope he loves her as much as she loves him. I wished I can reach inside the screen and slap some sense into her! LOL Luckily, the writers saw the errors in their way and she accepted him at the beginning of Ep 43. The down side to this meandering plot is that all the skinship was crammed into the last 2 episodes. So much time was wasted. When you consider this show suffers from the usual mid show drag, they could have done so much more with their love story. Converting a lot of that cute but ambiguous "we are just friends" moments mid show into sweet couple time would be real fan service and I would gladly give it an extra point.
