I liked the story - F4 (Four super intelligent, super handsome and rich exclusive group at Uni), in comes the middle class innocent girl Jan Di. There was so much angst between the lead pair (Jan di & Joon Pyo), its obvious that Joon Pyo was kinda obsessed with Jan Di, to extent of becoming mean, although he was super sweet too..... initially Jan Di had absolutely no feelings for Joon Pyo...throughout the series one would wonder whether who she will end up with Joon Pyo or Ji Hoo…. there were instances I wished that Jan Di would end up with Ji Hoo. He was one of the best ever K drama characters, calm, soft spoken.....standing by and supporting Jan Di all through the relationship hardships she faced....it was so obvious that he loved Jan Di deeply, & he let her go for Joon Pyo..Honestly one cannot help but fall in love with Ji Hoo .....I wished the other leads stories were more well developed. The ending again was rushed - like many other K drama's towards the end they have to find a way to separate the lead pair...in this case it is to pursue a career (which is great) - it was a happy ending, but would have been perfect if a wedding and some babies were shown between the Jan Di & Joon Pyo (after all the angst).
