So I picture their future one of three ways...spoilers...
1) Fetechuo ages very very slowly since he's now 3/4 human. Eventually Naerim passes on but he continues getting older and watching over their children/grandchildren/great-grandchildren until he passes on as well. 2) Old Naerim is about to die and Fetechuo finally drinks enough of her blood so he becomes fully human and they both die together. Not that he drinks enough to kill her but she naturally dies and they smile at each other, because it's fiction and it's always more romantic when the two lovers die contently in each other's arms. 3) Fetechuo outlives Naerim, wanting to watch over their descendents until he feels they're fine because he's protective like that then finally drinks enough from one of them to become human and dies.
I know these three scenarios sound bitter sweet but I would honestly be happy with any of them. I'm assuming Fetechuo is human enough they can have a family, which I think will make them both happy. They live a full human lifetime together, and Fetechuo passes on when he feels he's repented enough and with people he cares about.
