I really loved this drama and the unexpected yet delightful turns the characters took. The music throughout and how it pertains to each scene is really well selected and pivotal to whats taking places. You pretty much fall in love with all the students in each episode. The only downside to this drama is that it shoulda been at least 16 episodes long. There were so many interesting lines in the water storyline wise that it seemed to me a thrown together mess in the final episode 12. I was shocked to find it was only 12 episodes and I was like how are they gonna wrap this up and honestly it was too much thrown in the last hour. There was just not enough time to resolve any if all of the storyline issues. I was HUGELY disappointed in Sun Woo / Kim NaNa relationship never getting a chance to start after such a build up. I found once started Yoon Sul Chan / Min Se Yi were kinda the secondary characters for me I really wanted Sun Woo and NaNa to get together they had huge chemisty and their story of the girl from the wrong side of the tracks falling for the class Pres should have been developed more. Heck I woulda watched a complete drama of just those two's romance. And what was the point of bringing back Se Yi's mother and starting her storyline of the past with Han Ji Woong so late in the game? All it did was raise too many last minute questions about Se Yi and if he was her real father. And the Aunt who was always battling with the Gym teacher I thought more would come of them and their past together. There was so much greatness in this drama between the casting the music and the writing so as a fan / follower of the series you felt you got huge unresolved whiplash in how episode 12 was thrown at you and none of the storyline gave you any answers at all. This had such potential to be so more greater then what you ended up with and I find that truly sad. I feel this drama and cast demand for a second season and I doubt in drama style we were ever get one. I was hopeful with MNet and this being their first drama series that they would maybe surprise me and bring this cast back for a second season. I'd probably rewatch certain scenes for the music but over all I find it father sad and I'll mourn the loss of what might have been in the story. I so wanted the kid "Radio" to face off with his bully. I so wanted Sun Woo and Kim NaNa to get together. I would have liked to see what the whole real attraction was for every guy in that school to chase Se Yi cause that sheep girl only had outbursts in bullying situations but never really said ANYTHING other then "Huh" and "What" every time Sun Woo or Sul Chan spoke to her. Honestly what was her appeal??? lol. And No Min Woo ~ STEALS the show in the last 10 minutes you so wanted to see more of him in any way shape or form. I was watching this and was like "Ahhhhh!!! That's No Min Woo!!!"
