Lee Min Ho's haircut made me cringe but i got used to it eventually and lets be honest, he is a little too old for this role and it showed. I think the whole thing would have been better if he'd been a college student or something. All that being said I marvel at the comments on here about there being no chemistry between Kim Tan and Cha Eun Sang....Seriously where were you guys just before Tan's mother caught them in Tan's room? And on the school's roof? And my, oh, my, in the cellar? And later on in Eun Sang and her mother's apartment? ("Dont do it!" "Dont do what?" "..My mother will be here any minute!" "I'll lock the door.") And Kim Woo bin is a great actor and extremely attractive and all and I quite look forward to seeing him in other dramas but theres something a bit too villainous about his features that makes me think it'll be very difficult to make him the sole lead in a successful romantic drama and the comments here about him solely carrying the heirs is just plain ridiculous and dense. Lee Min Ho is as ever, an incredible actor, - as at home in front of the cameras as he is in a suit and Park Shin Hye has become the great actress I'd always known she would grow up to be after watching her in stairway to heaven. The storyline was simple and cliched, true, but I think that is the beauty of it. Not every drama out there is going to be the next great original work of art - if that is your belief you should give up now. There is nothing wrong with a drama just being entertaining. This show is no City Hunter but its a fascinating new take on something we've all watched a millon times - it is new, mordern, funny, quirky, youthful, sometimes sad, and oh so romantic. It is itself. It's a great show - my only regret is that it wasn't produced four years ago, when Min Ho was the right age, and Min Ho if you ever see this I hope you've finally graduated from highschool once and for all.
