Okay Kitsune, here's the best I can give you. Long analysis cut short, the pursuer (I'm going to assume male here) is completely enamoured with a lady that I'm randomly going to call Cassandra. I take the fruit (ughunclekenny) to be a metaphor for his love, which he offers to her eagerly, desperately, pleadingly. But it turns out to be Cassandra's ruin, and the third stanza reminds me of drug-induced hallucinations. It seems like his love for her was too overwhelming, perhaps possessive. So initially in the poem, everything seems so romantic, and the way the persona offers his love makes people (at least, me) go awww. But all this obviously changes by the end. The fourth stanza is probably where things are supposed to change, but when I read the third one it already made me unsettled, like there was something very wrong - a sign of foreboding, perhaps. And in the end the guy is left wondering what he did wrong, how could his love have hurt the one he loved? And he comes to some kind of realisation, that the love he coaxed onto Cassandra was ill-fated from the start, and has only led to her ruin.
Maybe it's a parallel to relationships where people think, oh because they love each other, nothing can possibly go wrong. But things get possessive and abusive, and one person's love ends up destroying the other person.
Okay, this is a crappy review/interpretation and the most incoherent thing I've written in a while. I blame it on Uncle Kenny's chicken.
