Basically it feels like any other ordinary love stories, it takes about the struggles of each lead, where the movie shows woman will bound to have some sort of work harassment or cheaters in their life! While the man have got (not only women get cheated!) cheated by her fiancée... the movie shows what happened when two individual met at working environment and gradually shares their own personal relationship struggles, then how their bond form and as much as western culture may show their affections straight away, the korean culture will be form by a lot of "water testing" etc..
Must say, it's a chill and relax kind of romance I don't think the word "crazy" matches the movie... isn't a bad one! great time killer and chick flick!
