I say innocent cuz of the shenanigans he pulls off ? like drawing a magic band across their wrists with a marker cuz a children's witch book says so .. is innocent. His grown up age doesn't match his mental age. He does want affection in the form of kisses & hugs though but so far maybe it's censorship or maybe it's the line author drew - we haven't gone further than that.

BUT at the same time it'd be stupid to pretend that Big Potato doesn't have romantic feelings towards Papa Wolf. HE DOES. It's clearly not reciprocated so it's not pedo or whatever. But it's there. So you can ship if you want, or not if you don't want. You can also dive into the psychological issues that goes beyond an abandoned child developing feelings for his saviour but it won't change the fact that he does have feelings and quite innocent one at that.
