In The Kite Runner, is the reason why Hassan keeps sacrificing for Amir because he loves Amir deeply (not in sexual way)?

Hassan better understands the relationship and social
standing between the two boys than does Amir. Hassan recognizes his position as the son
of the household servant, Ali. Though Ali and Hassan are treated with great kindness by
Baba (and we find out later in the book one of the reasons why), they do not live in the
family home; instead, they reside in a mud hut on the property. Both Hassan and Ali are
reminded regularly by others of their lower-class Hazara ethnicity, so they have no
illusions about their place in Baba's home or in society. Hassan loves Amir for a
variety of reasons: He is proud to be a friend to the son of a man with such power and
wealth as Baba; he appreciates the time that Amir spends with him; he enjoys the stories
that Amir reads to him; and for Hassan, Amir is his closest friend. Because he is a
servant's son, Hassan has an innate sense of service, another reason he is always
willing to run Amir's kite.
