Unsinkable Bones(2003)

A Journey of two people at opposite ends of their lives. Shota (Kamiki Ryunosuke) is a little boy who runs away from home, due to both of his parents' neglect. With just his piggy bank, he bravely walks out of the house without either of his parents noticing; as both of his parents are doctors and are busy checking patients. On the other side, Jun-chan (Naoki Sugiura) is a terminally ill old man who decides to run away from the hospital. Their paths cross and then somehow they end up travelling to the countryside together.
