This was the first Kdrama that I ever watched and I even after watching more than 50, this is still my favorite. Hwang Jung Eum is truly the reason this drama is so good. Her character is sweet, lovable, and funny, but doesn't come off as just another "typical innocent girl". I also adore Choi Si-Won in this series. He brings lightheartedness to the drama in a really fun way. Park Seo-Joon is a pretty good actor it seems, and I do like him as the lead here, but his English is just SO BAD, especially for someone who has supposedly grown up in the US. I just wish they would have given him some better lessons, it would have helped make that part more believable. However, this drama is still at the top of my list and I HIGHLY recommend for anyone starting Kdramas! :)
