I watched this when I saw the clip on my timeline. The clip was interesting, it was about fat girl being bullied, and then she changes to be better. That's why I decided to watch it.

The story is quite normal, about the fat being bullied, and one day a 'so called angel' helped her to free herself, since the fat girl was so depressed. And the angel gave her magical things that let her has extra day a week, which is the eight day.
And then, more troubles happened, just watch it! heheheh But actually I don't really recommend this movie, since at first I thought there will be romance. BUT NOT AT ALL. quite disappointed. and I don't like the main girl character at the beginning. But, I love how she becomes better without that magical help.
