Task: Question Generation
Input (English): Passage: When socialite Army Air Force pilot Oliver Bradford is disfigured by war wounds, he hides from his family, including his mother, after his fiancée is too jarred by his disfigurement to accept it readily. He lives in bitter seclusion in the seaside New England cottage he had rented from its current owner, Mrs. Minnett, for his originally planned honeymoon, while blind concert pianist John Hillgrove who lives nearby befriends him gradually.
Laura Pennington is a shy, homely maid who has hired on as the cottage's caretaker and befriends an initially reluctant Oliver after he admires her wood-carving talents. Oliver and Laura gradually fall in love and marry, but after Oliver and Laura fear their marriage is one of mutual pity, the couple discovers that their feelings for each other have mysteriously transformed them. He appears handsome to her and she seems beautiful to him. This "transformation" is perceived only by the two lovers (and the audience).  Laura believes that the cottage is "enchanted" because it was once rented to honeymoon couples, and in time the widowed Mrs. Minnett reveals the true story behind the cottage's enchantment legend.
Output (English): What is the full name of the person John Hillgrove befriends gradually?
