I rated 10 on all of it. Here's the reason why: Story: The story is so refreshing, it is very light yet you still have the urge to watch it and it not like other light cliche dramas. I love the idea of using sports! I love how the story tells about what athletes feel and how do athletes live despite of their problems in life. This youth, sport, light drama is perfection! ACTING/CAST: Joon Hyung and Kim Bok Joo are PERFECT for each other. Their acting is so real that I thought they dated in real life. I love their connection, especially when they are in a relationship. The kiss feels so real, the hugs, etc. Kim Bok Joo (Lee Sung Kyung) is so cute and beautiful at the same time, I love her acting cute because she is cute! Nam Joo Hyuk is perfect on the Joon Hyung character. He is really good at teasing, he made me cry, etc. Kyung Soo Jin plays perfectly on the Si Ho character, I love the acting of her being obsessed and depressed from her problems. And other actors/actresses did well too. Really awesome. MUSIC: THE OST IS SO CUTE and it brings you to a different world. I even downloaded the OST and some background music (I don't know if it is weird or crazy to download the background), because you feel like you are also in the drama and it really relaxes you. The soundtracks are cute and it makes you cry for some songs. It is perfect. OVERALL: It... is... PERFECT! I can't stop repeating the drama. It has been months now and I still can't get over it. You should watch it if you are into youth and light dramas. It really deserved to have higher ratings on Korea. It's sad that it is a bit low on ratings on viewers.
