Black Jack (TV) - episode 36 - 17 Jul, 2005

Pinoko becomes frustrated at the poor state of their house and begins pestering Black Jack to move. Black Jack instead tells her the story of the carpenter that had originally built the house. He insisted on being the one to renovate the house into the clinic that Black Jack desired, but ended up becoming the first patient due to leukemia, which at that time was still largely untreatable.
