Addictive- yes, that was watching Sungkyunkwan for me at FIRST sitting. Imagine, I've finished 8 episodes (that was about 8 hours and so) straight! I had my sleep at early 3 in the morning, and again, another night-wrecking the next day (it has 20 episodes in lenght). The quartet really got the charm to hook you up! Lee seon joon? (played by Park Mickey Yoochun: JYJ member) smart and disciplined student who was the center of envy of the school president, who found himself fall for another man...Will he stick to his principles? Or will he disclaim principles for love? Gu Yung Ha? (played by Song Joong Ki) gay or just too GAY(sweet and touchy)... He cherish his best friend Jae Shin so much! He was smart and tacky, and so cool that he was the charm of the this TV series. Moon Jae Shin? (played by Yu Ah-In) tough rebellous guy with the bare chest flung on screen, :p he was so damn rugged cutie who has pure luck beside him (everytime he terrorizes at night). Kim Hyun Shik? (played by Park Min Young) the main lead who used his brother's name and pretended to be a boy, due to untended events, she pursued pretending inside sungkyunkwan university that led to that so called 'SUNGKYUNKWAN SCANDAL' with Jae Shin. I really like Song Joong Ki here, he was oozing with charm and cuteness while Yu Ah-In's smile melts my bone! ayieeeh! It really had a good start but the end is a disappointment! I am not satisfied with the smooth take of the events on the last episodes. Though it gave cues to what happen to the quartet, it didn't gave anything about how the student president end up with along with the other characters (hmmm.. I guess the episode which he save the gaeseng suggests that he ends up with her..oh well!). I believe many will agree with me about this. Another thing, the story run so smoothly to the protagonists, nothing heart breaking at all (well, if it really should be lively, we can do nothing about it), the rush in every episodes and the uncomprehensible (i can't understand it!) ending. Wew!
