What I loved:
1) After watching show after show of open-eyed, deer-in-the-headlights, arms-hanging-limply-at their sides kisses, this was a welcome change! The kisses were wonderful, realistic and full of steaminess. The only reason I rated this as high as I did was because of the chemistry factor.
Not so much:
1) Story - there wasn't one. They went from strangers to living together with no getting to know one another. If the storyline was just about sex, that would be okay, but we were supposed to believe that they were in love with each other why? The secondary characters were there to put some tension in the storyline I think, but that didn't work either.
2) Characters - male lead: he was the typical male character, nothing special about him. Female lead: I felt that she was not very bright. Her behavior was strange and she was overly friendly to everyone. She had no family or friends? I was, however, glad they portrayer her liking physical intimacy as well, and it didn't all just fall on the man. The co-workers: the men were creepy and the females were silly.
3) Ending - as Asian dramas almost always do, the ending was very rushed.
So, if you just need to see some good physical expressions of affection, this show is short enough that you don't have to make a very large time investment.
