English is NOT my native language
Hoshi mamoru inu is a Japanese term used to describe a person who wants something impossible to have. This meaning comes from the dog that gazes up at the sky, as if it wishes the stars. In the end, we are all dogs, desiring something we can't have, unsatisfied with what we have.
With 125 pages long, Hoshi Mamoru Inu is a manga about an old man that lives a very simple life. After certain events, the man found himself with a car, a dog and a few bucks. It's a very simple story, with high emotional values. The second part of the manga is where it lost me, since I honestly couldn't care about the characters anymore when their story is told by another point of view, I would rather that the manga developed the main story until the end instead of ending it very early, that would result in an even more emotionally-packed manga.

I would definately recommend this manga for those who are interested in a very enjoyable, quick read, a drama that will make you cry in a few pages.
