This drama is really awesome. I had to write a review about it. First of all, acting is oustanding. Main leads, both great actors and have great chemistry. Story is really cool with main guy Min Joon being an alien and living on earth, it's different and unique. To me, every single episode was interesting and endings of each episode were a cliffhanger and i couldn't wait for another episode. I should also add that there are no usual k-dramas cliches, bad guys ruining their relationship and doing everything to separate them, no there really aren't. Other supporting roles are really acceptable and interesting to watch. It was really refreshing to watch something completely new. I could be adding now a lot of things, but i will just say one thing: If you still haven't watched this, go and give it a try! You won't be dissapointed. I gave it 10/10 because it is this good. It became one of my favorites :)
