*Might contain spoilers* I want to be honest cause I really enjoyed this drama just as I enjoyed the japanese version and the manga. You will probably enjoy it even if you know the japanese version or the manga but I think you'll enjoy it more if ye didn't know. Like some other reviewers will say a lot of important things are left out that makes Hana Kimi so much fun. On the other hand I understand why the korean version wanted to make things a little different. But because of that only the relationship between Kang Tae, Goo Jae and Cha Eun filled the entire series which I thought was just not as exciting as it could have been. Because now they are the only main subject in the story leaving no other relationship to sidetrack you in a different story development (the story with his dad felt very weak to me). And I really really missed the Doctor being extravagant and being bothered by his ex and I also feel they didn't properly portrait Song Jong and they did not even properly wrapped that up at the end of the series. I mean if there's one person that'd be bothered by the whole revelation it has to be him making a scene right? Anyway a good watch don't be alarmed by my ratings cause it is fun. And I really like Cha Eun especially when he went to his parents I wish we could see more of his home situation cause his parents reacted funny hehe. Oh Min hyun's character background was also left unexplored pity even his story was not properly wrapped up >_
