It has literally anything you could want in a romance packed in 20 minutes, and yet it doesn't feel rushed at all! I don't know if it was intentional, but it felt like watching a dance performance in itself. I was giddy the whole time watching them get closer.
The only thing it really lacks is a good soundtrack, but with the music they do use, it gets the job done. The biggest plus on this one is the rewatch value. I could probably watch this multiple times and never get bored of it.
