I don't know how to start. This mini drama was very surprising. I'm a bit disappointed by the fact that it was so short, and some things were a little bit unclear (plus, there are not a lot of dialogs). But yet, it was really good!! The story is somehow sad, but really beautiful. Seo In Guk and Wang Ji Won were awesome, portraying a couple who just met, but somehow feel related. Seo in Guk appears to be a very good and apparently lost but adorable alien, who wants to find out what tears are. In addition, the music is really beautiful. There are, as I said, not a lot of dialogs between the characters, but there is music almost all the time, and it conveys amazingly well the atmosphere and the feelings of the characters. So in the end, I advise you to watch this, you will be surprised! It is beautiful, and you can't say it's a waste of time, as it is only 50minutes overall!!
