WHAT A SHOW. It was just one of the all round best shows I have ever seen. There is not one one thing I can pick out that I would have wanted to be different. The acting, the development, the twists and turns were just perfect. I have a habit of reading many reviews before watching the show and I read many mixed reviews but decided to give the show a shot anyway. Thank god I did. After watching the show I just can't understand and relate to any of those faults they found. I genuinely found the show just amazing. Story: The main complaint in the negative reviews was the lack of story. I am not one for melodrama's so a story like this that is light but intense of the romantic side and extremely focused on main couple is something I am very content with. I don't believe you need major second lead jealousy, manipulative parents and all the crazy K drama go to cliches for the story to be interesting. I quite enjoyed this break from the typical angst. Something I was personally worried about before watching was the 'health' concept. I really didn't want it to be too preachy and to make you feel really pathetic for not being motivated like her but that god they approached it in a light enough matter. Characters: This show made me realise the importance of chemistry. Honestly there could be nothing else and just the main couples interaction and the show wouldn't be boring because the chemistry was electric. It was like nothing i've seen in any drama or movie before. I didn't for a second feel like they were two actors playing a part.. I recently watched and dropped 'My lovable girl'.. A show that also showed me the importance of chemistry but in the opposite way.. This has lead me to make the hypothesis that chemistry between the main couple is what can make or break a show. Can we now mention the eye candy? How hot were all 3 of Kang joo eun's men? Cutie pie ji woong, Mouth water-ingly hot Joon sung and of course our flawless coach-inim
