I don't watch this drama right away after knowing its airing date. It had a very bad premiere rating, competing with SFD and GT with relatively unknown casts. I initially ignoring it completely. Such a low rating, I have a very bad initial impression on this drama. However, I don't know why I started to read the recaps while ep 4 aired and it immediately hooked me. The story is engaging, fun to watch and the visuals didn't hurt. I am completely fall for lee won geun's eye smile. Kim Yeol is really attractive male lead. He is smart and he knows it. He didn't turn stupid because of love and didn't do stupid things. He knows what to do after seeing things. He really use his brain well. I do think that other male lead in drama should learn from Yeol on how to express feelings and how to use their brain. Seriously, having more of a flirty, smarty and cute male lead like Yeol won't hurt anyone. Yeon Doo, on the other hand, was a fun and thoughtful student. She talk about things. She care for her friends. She is willing to do what she think is right, even if it will make her life difficult. I do think that she need to think more (she can always learn from Yeol), but she still on the right track for me. about Ha Joon.. well... I don't usually feel second lead syndrome and I don't feel it in this drama. His friendship with Yeol is fun to watch too. Now for Soo Ah... She is crazily pressed by her mom. She has nowhere to turn to, and end up being the villain in this drama, though she did show some complicated emotion during almost every mistakes she made. Overall, this drama was really fun. It shows a lighter side of school drama (I personally think School 2013 and Angry Mom kinda dark for me). School shows should be like this :)
