I watched this on netflix and then afterwards I went on wikipedia and saw that people called it the worst film of 2007. Really? Cus I thought it was sweet! Now that i'm no longer in high school i often think to myself how much I want to go back and tell myself to not do this or to do that and this movie is basically voicing the same sort of feeling of regret and wanting to change. I really adored taehun especially the younger him (such a good looking guy it's hard to make him look nerdy!) and I appreciated the fact that with this movie the 'love triangle' wasn't typical and that the second guy was finally noticed for all the things that he does for the one he cares about. I liked the message of the movie that sometimes you might want to change your past but even if you could go back if it was meant to happen it will happen and there's nothing you can do but you should never regret.
