Where we find the love in this novela?

I really think the boy Manolin loved Santiago. Santiago taught Manolin to fish, and the boy used to go out to sea with the old man until his parents objected to Santiago's bad luck. Manolin still helps Santiago pull in his boat in the evenings and provides the old man with food and bait when he needs it. Manolin is the reader's surrogate in the novel, appreciating Santiago's heroic spirit and skill despite his outward lack of success. Santiago also identifies and loves the great Marlin that he killed. He sees the Marlin as a brother wothy to be killed as well as worthy to kill him.
