A lot of people seem to take the comment about his heart being "pure and innocent" as meaning that he's totally ignorant and inexperienced, but I see it as being about his nature as a liminal being, between human and Pokemon. Pokemon are incapable of true evil, and so N, who is a "freak without a human heart" who was "born from pokemon", is too.
Also he's hot, dedicated, likes animals, knows nothing about the world (in a good way) and is obsessed with you
