I usually find characters similar to Lee Min Jung's character, Gil Da ran, either annoying or frustrating. Especially if they are as beautiful as her, it makes it really difficult to wonder how men are not attracted to her even if her stats are below her peers. She's so pretty and her personality is so warm. She may not be calm and collected, but where she lacks in one area she makes up in other areas. Her character reminds me of Ariel Lin's character (Xiang Qin). Her feelings toward Gong Yoo is parallel to Ariel's love to Joe Cheng (Zhi Shu) in ISWAK. But Lee Min Jung's character has its differences from Ariel's Xiang Qin. All in all, I'd say I enjoy Lee Ming Jung's take on this character so far (being only Episode 2). She is not annoying or frustrating but quite endearing.

Gong Yoo's character is both challenging and fun to play since he has to mimic Shin Won Ho as Kang Kyung Joon. There are times when I see Kang Kyung Joon's character pop up within Gong Yoo, which delights me. But most of the time, I give Gong Yoo the benefit of a doubt that he is possessed by an 18 year old as the story demands. His not so subtle childish behavior though can be a little overbearing considering the sassy and witty Kang Kyung Joon we met at the bus stop and observant student we saw in the classroom watching an emotionally hurt Gil Da Ran being teased by her students for the radio story. Shin Ho Won is the top of his class back in the states. He is not so immature, just very guarded and somewhat damaged from the death of his mom. I can imagine Shin Won Ho acting mad but I can't imagine him pursing his lip and blew making that buzzing sound. (This happened at episode 2). Very immature. I don't think that's within Shin Won Ho's character. I hope Gong Yoo does not go overboard on the immature for his possessed character. I want to see the boy in the man, not the man trying to be a boy. All in all.... I'm lovin' it.
