I didn’t really get this story, and I don’t think there’s much to get. On the forums, readers suggest that it’s about the main character’s girlfriend’s pregnancy and/or their future together, but it ends a bit open-endedly for me. Perhaps the end means the couple is infertile and Guenevere will take him with her to the grave childless.
