Maybe what the author was referring to was who dies? Just because they were together in the past doesn’t necessarily mean they need to be together in the present especially since we know Agia is only tricking Ken into this relationship so they can both be sacrificed since Agia wants to die. But maybe that’s what the author meant by they may not be endgame is Agia may find another way to die and allow Ken to live because he is clearly also falling in love with Ken and no one wants to drag their loved one into a sacrificial ceremony right? So author nim may be alluding to an upcoming death or who knows maybe it really could be a surprise switch up or love triangle. But that’s highly doubtful.
