I honestly love this movie. I've rewatched it soooo many times I can't count it.

1. The story is straightforward with a small number of important people. By that I mean, no irrelevant people slow down the plot. The main antagonists make you understand the worth of the female lead.
2. The romance is light but so heartwarming. There are no kiss but you can feel the romance blossoming from beginning to end.
3. I usually don't like Japanese content because of the overly "Kawai" or some weird stuff that could make foreigners (by that I mean those who are not used to Japanese culture) uncomfortable. But in this movie, there weren't any, like the abuse was reduced to necessary without making it overly uncomfortable. [I don't want to offend anyone, but JP content is really special]. There's not too much overacting.
4. Did I say I've watched a thousand times?
5. The story keeps so captivated from beginning to end. Tho there are a few questions left unanswered no matter how many times I watch it.
