If we closely analyze the story up until here we could see the development of the characters that somehow completely undermines - what feels to be - the legitimacy of their growth. What I mean by this is that the roads that they take to get to their radial correspondence in this story is slow; There is so much things happening that their existance as a circular receptacle feels too forced but I believe that the writer deemed it was neccessary for the plot. I am team Cain all the way because of his benevolence as a lover and as a person, but we can't completely forego and foresee the inevitable exasperating ideology and foreshadowing that the writing is doing here. Though - maybe different - the ending will, or might, be with one that is most unexpected.
