"Goodbye" is something that could happen to anyone tomorrow. And the feelings that remain afterwards. Through the serious subject of "forensic medicine," it carefully captures the feelings of love for others and the time they lived, quietly shedding light on the darkness of a "society where the cause of death is unknown".

Having failed with his business and gone absolutely penniless, Masao (45) divorced with his wife, and is currently leading a hopeless life in Ibaraki. One day, a mysterious high school girl, going by the name Emiko, showed up before Masao. Every now and then, Masao would be toyed around by Emiko, but little by little he started taking a liking to her loveliness. As days went by, Masao started opening up to Emiko – something that he rarely did to others. However, there was just something about Emiko – something that bothered Masao - that wouldn’t go away.
