I don't think my snakes love me. I do think my snakes recognize me, perceive me as being of no threat and associate my presence with things like rodents, water, and getting out of their enclosures. They do not all appreciate me equally, but every last one of them behaves differently with me than other members of my household who handle the snakes minimally and never provide food/water/take them out. They're simple animals, yeah, but they are animals and are very definitely capable of learning and forming associations. If they've got a positive association with my presence (and getting things) then it's good enough for me.
