I love this drama so.

Story: It was different, but not original. I also like The Hong Sisters(the people who wrote this drama). I think this was their best drama yet. The characters where fleshed out well.

Acting: The leads(Go Hyo Jin & So Ji Sub) have amazing chemistry. I haven't watched many of their dramas yet, but I will soon. I heard So Ji Sub was in a lot of melodramas, but he was so funny! It took me by surprise that I laughed a lot in this drama because of him! The other characters were funny was well.

Music: It was good, but not memorable. The ost was great, but I wouldn't listen to the songs over & over.(my opinion only!)

Rewatch value: This was an adorable drama. I would rewatch everything! Mostly the funny, cute & sweet moments. But I would rewatch it for the love story as well.

Watch it if you like the following:

The Actors in it(So Ji Sub, Go Hyo Jin, Seo In Guk & the 2nd female lead(which I can't remember on top of my head)).

The Comedy. . .

The Romance. . .

And

The Horror/paranormal aspect. . .
