"Life is full of pain, but there will always be hope, somewhere."

Takashi Aoyama has way too much work to do and pushes himself mentally too hard. He blacks out and collapses at a railroad station. When he is about to be hit by a train, he is saved by Yamamoto. After his encounter with Yamamoto, Takashi recovers his bright personality and gets better results at work. One day, Takashi sees Yamamoto boarding a bus to the cemetery with a serious expression.
