It’s a typical deeper meaning Japanese movie. I forgot that I already watched this film a long time age. That’s because I watch a lot of movies and series. But the feeling of how beautiful the deeper layers in especially his behavior (being damaged in his past, with forthcoming behavior as consequence) struck me directly again.

The movie is softer than the manga, from what I read. It also doesn’t the complete story and the years after. I’ll leave the manga and the behavior in that out of the evaluation and rating.

He was ‘wearing’ a shield to defend himself, because of harm in the past. That shield was his behavior, in order to not get further harm in his live. Behavior always has a reason. He’s not just a jurk, born this way. Behavior is often a reaction to (a) certain event(s), which brought about thoughts and feelings. If you change your behavior, you change your life. That is not easy. It requires awareness, insight and the courage to dare to change. That's what we've seen here. This takes time. Fall and rise. At the end of the film, this process is not yet complete. Not with both, because se also changed, with as outcome the decision she made in the end (I won’t spoil that).

I love the acting of both. Yes, he looked like a cold person. But that was his shield role, right?

The music suits the film.

I’ll surely will watch this movie again. .
