I didn't have great expectations for this movie to begin with - and still it managed to really disappoint me. First of all, I couldn't like the main characters, and that is always a problem. I just couldn't relate to their lives or problems at all. In my eyes, Ha-Young was just irritating, spoiled little girl screaming, making faces and throwing tantrums all the time. Hyung-Joon wasn't any better, he was definitely arrogant (as the movie's name suggests), mean and self-centered. I could have still forgiven these flaws of theirs if they had had any good and amiable side in their personalities but I just couldn't find enough good in them to make me like them. Secondly, the whole setting of the story was just too weird and twisted to my liking. I'm normally okay with dramas or movies that have all sorts of marriage/sibling/dating/cohabitation agreements in order to provide the main characters enough interaction so that they can fall in love with each other. However, this "Enslavement Agreement" was too much for me. My dislike for this agreement was further strengthened by the fact that the girl was still underage and the boy in college (call me prudish if you like). Had they had a pure, equal relationship, then it might have been okay, but in this case, the setting was just too weird. Thirdly, I wasn't convinced that the characters really fell in love with each other. I acknowledge the obvious time limitations of a movie compared to a drama but still, there just was something missing. Fourthly, I really didn't get the humour in this movie. Even the numerous day-dreaming scenes of the main heroine didn't really work or weren't that funny. I was actually really surprised to notice that Ha Ji Won played in this movie. I liked her in "Secret Garden" so I'm tending to believe that this movie wasn't so bad because of the acting but because of the storyline. For those who now think that I seriously underrated this movie, please feel free to give it a better review. I am no longer teenager, nor am I Korean, so maybe there were just some things I didn't get, but personally, I wouldn't recommend this movie to anyone. You'll just feel stupid afterwards for wasting your time on it.
