SPOILER ALERT!
So after putting it off for a couple says I finally watched the last 2 episodes. I am very happy with the ending. I was hoping that it wouldn't turn into another Innocent Man ending and it didn't! It was logical and so cute at the same time. It wasn't a perfect happy ever after and I think thats why I loved it so much. If he just all of a sudden could stay on earth and it was all good it wouldn't have maken sence. It would have been sweet but too fake. The fact that he had to work and it took time makes it so much more real (as real as a drama about a gorgeous alien can be). I love her opinion of it as well. "It makes me love him more. Thinking this might be the last moment with him" is the strongest ending quote I have heard from any female lead in the k-drama world. I love the idea loving a man with all your heart but being strong enough to deal with the obstacles even when you arn't together. And when you are together spending that time comforting each other and being "perfectly happy." This has been the least realistic and at the same time the most realistic drama I have seen so far. It has a very good storyline and was put together very well. I loved the actors, the director, the writers, even the flippin background people. Guise, I loved this drama.
