It was funny, cute and lovely to see both Moon Chae Won and Yoo Yeon Suk acting together.. I'm big fan of both actors and their work. And I think that their pairing was a pure gold. The impression that this movie left on me was good. But as for the story, it's already seen. Also it's really risky to do a rom/com movie based on a topic of a one night stand, because in a real life one night stands are strongly disliked and don't have any relation with romance. But on the other side I think that they made a serious topic, that is like a big thing nowadays, interesting and that they pointed out the problem that is very common and normal today in our society. As for the acting... Well, there's nothing to say about it. I mean, Moon Chae Won and Yoo Yeon Suk are both great actors and I can only say "Bravo!!!!". Hahahaha. XD The chemistry between the leads was amazing. And I would like to see another project with this two actors. So here, in this movie, the writer is giving us the opportunity to see a good and a bad side of people. Of course, one is a bad side or should I say a cold side which people use as a wall to protect themselves from being hurt and the other is good, soft and warm side which a person rarely shows to the other people. As the movie goes on, they slowly begin to develop a feeling towards each other, as they get the opportunity to see good qualities of that other person. OST.. Well, I liked it. But also I didn't pay that much attention on the OST, cause I was more focused on the theme of a movie and chemistry between the leads. Overall, it was refreshing to watch a movie like this, with this kind of a cast. And I recommend watching it, cause in the end you will end up liking it.
