I didn't like this film very much the first time i watched it. But after finding out some hidden easter eggs and plots from internet boards, and watching it again -my brother rented the video- boy! it was a whole different movie and i liked it pretty much! some things that you might not know includes...

1. The time machine plot: That strange old man is Gyeon-woo from the future and you can see him at the subway scene that the couples meet for the first time. this made the little bit seems-too-loose third chapter more meaningful and enjoyable for me. 2. the old framed newspaper article that appears during the scene where Gyeon-woo first checks into the hotel that shows quintuplets. The inn keeper is actually one of the quintuplets and you can find the others throughout the movie-although i have only found 4 ^^;

so even though you have seen this movie i think its worth watching again, and those who have not seen this yet, this has all the things - Cute, Romantic, Funny...all in one, plus the lead actress is really cute!
