If you love dogs, you'll love this movie. It's from the same producer as "Quill". The story is based in Japan with Mayuko Fukuda, who plays a 14 year old girl Akira. She meets a little pup in her life, but was sworn to 10 promises if she wanted to keep her. Rena Tanaka who plays the older version of Akira grew distant to her 10 year old companion and the rest you'll have to watch. It's a sad story, love story, a touching one, and something funny happens during the end!!
I love this movie not only for the dog, but also for the music! It's a movie anyone can watch!
