Black Jack (TV) EP18 - Friendship by Mail

Although Jun is in wheelchair, he tells his Internet friend Tom he can play baseball. He did this because he was envious of Tom's stories of living on a ranch and helping out with all of the chores there. When Tom is about to visit, Jun asks Black Jack to heal his weak heart. The price is too high, and Jun breaks off his friendship with Tom instead. When Tom finally arrives, Jun learns that he is the young, blind inheritor of a large company. Tom offers to pay Black Jack's fee for healing Jun, at the expense of his own eyesight. Black Jack heals them both.
