I think this movie is so good that i have watched it twice. As a teenager becoming adult i can relate how they both struggle on their own world. Yukino is just a soft woman that didn't let her age and her profession let it bother their bond throughout the movie (only the time when takao confessed his feelings to her). And that climactic part, it was a beautiful moment. I recommend every one to watch this movie even if you're not that much of a anime lover.
Edit: This movie's animation is so advanced and so beautiful. it was so realistic. I wish there were more movies like this. I was just astonished by the visuals to the storyline and to everything.
