Choi Shi Won and Go Joon Hee were making the show really worth watching. It's a light, positive and fresh series to watch, nothing too complicated but is pretty moving. I like that story is about a person who tends to be overlooked, it's a lot of emphasis on that. Even as the story progressed and it may look scattered, I get the emphasis on "watch the overlooked people". I find myself moved by the characters who is on the side (Shin Hyeok mostly, and Ha Ri) instead of Hye Jin or Seong Jun. Shi Won was super CHARMING and believable in his character. He made the character as deep and heart-moving as it should be. I adore it (10/10 from me). His character SHOULD BE made into a spin-off. Total love. In fact I finished watching the show because of him. The girls friendship is super adorable and really isn't often seen in dramas I watched (perhaps even never). I also love the fashion seen here, especially what Hye Jin wore during The Most 20th anniversary event. Shin Dong Mi was really good as well, very interesting to watch and actually notice-able in all her scene. Now things I like the least is Hwang Jung Eum as Hye Jin (3 /10 from me). I find her character has multiple personality disorder, depending on what looks she has at the time. When she's young (smart, rich and pretty), she's elegant. And when she got less pretty she got goofy, overacting, loud, and clumsy (what happened?!?) and then when she used makeup, she will act like a normal person. What's with that?!? This fact is the reason I barely hold on to watch her scene, except when Shi Won (as Shin Hyeok) was around. To conclude, I enjoyed the show for Shin Hyeok (I know, I may be his fan now) and the friendships shown. Its fresh, light, nothing complicated story line was perfect for me. But truthfully, lead character Hye Jin needed a lot of help (psychiatric *cough*) and since she got most scene, well...
