the story is really good, i like the fact of her personality being cheerful and sometimes goofy and not being always worried about her weight (at least in the beggining of the film. the cast was good, i love the main character, but i think the guy could have been better... the music was amazing, it sticks to you and you'll be singing it non-stop for the next few days. i probably would rewatch it if i didn't have anything to do, but it wouldn't be a must. overall, it's good, worth watching and funny. one of the best korean movies i've seen.
