Cheon Song I is the best actress in the country. When she moves, her new neighbor, Do Min Jun, complains that she sings too loud at night, which she can't understand well, since the walls are said to be thick in her building. Little does she now that the guy next door is an alien, that lived on earth for 400 years already and is just waiting to go home in three months, when the asteroid, that brought him to earth, passes by again. But as destiny wants it, they get involved with each other through various events and the wonderful love story may begin...

The story is rather basic, but it has everything it needs to make my heart skip beats like crazy. Do Min Jun is the mysterious, silent kind of character that slowly starts to loose it when his love gets in danger. His feelings grow slowly, her feelings grow slowly and even though I can't pinpoint where they fell for each other, I didn't feel surprised by their deep love for each other.

Aside from the love line, there is a surprisingly high number of deaths in there, since there a side character, that spices things up by intriguing here and there to stay on top of the company.

Side characters like Hwi Gyeong and Yu Se Mi are actually also lovely. I enjoyed their story and that they weren't as dramatic when they couldn't get the guy they wanted to have. I especially liked that, for once, there wasn't somebody chasing after the male protagonist, being nasty to the female lead and everything.

One thing many might be curious about is the ending. Since it's an alien drama, I also was expecting either a very dull explanation or no explanation at all. If you are worried about it, here is my opinion: I liked the ending. It wasn't the usual dull answer, it wasn't too easy and I really liked the outcome. Maybe they didn't think it through perfectly, but if I compare it to other supernatural themed dramas like "My girlfriend is a Gumiho" or "Big", where they messed up the endings, if you ask me, I think they did really well! I was content.

5* for this lovely drama, since it's a romance drama just the way I like it. A bit of action, a bit of humor and lots of love mixed with an okay-amount of tears. Recommended romance drama for every romance lover!
