The phrase from "Where the Wild Things Are" comes to mind... "...please don't go. We'll eat you up, we love you so!"

Spoiler for Cannibalism ahead::

It is said that in some cultures, cannibalism is tantamount to showing love. In at least one cannibalistic culture, a couple would be chosen and as they enjoined upon a pyre, they would be killed and roasted for the village to eat, all as a symbol of love, fertility and as an offering to the gods who provide food.

The zombie stuff is just further damnation of the myth and mystery that follows this barbaric practice. Many female insects especially, eat their mate during fertilization. This was even alluded to in an episode of Franken Fran, although this is the first time I've seen such a subject handled first person through the protagonists of the story. Very creepy path being taken by this manga.
