It is about two demigods that are going on a date after having not been on one for quite a while.  I liked the idea of the fictional universe that it takes place in and the dynamic of the relationship that could possibly be strained with time, but is found to not be strained at all.  What significance does them being demigods have?  I just feel like the story was less about that and more about the relationship.  I would just suggest condensing it a little, we spend a lot of time with the anxiety of the narrator and the planning of the date, but not really much time getting to know anything outside of them.
