I'm glad for your interpretation because I don't even know what is going on with all of that right now.The chapter is really confusing, is Reiji's real father really some random distant relative of Esemori who is never ever mentioned before that died of some terminal illness? Yuuko seems to think that it was actually Esemori who for some reason pretended to not know her and pretended to be a relative of his.
But then again, she is kind of delusional so maybe none of the above is even true and she got pregnant from having sex with some random patient who looked similar to young Esemori.
So, Esemori is reiji's dad?
I am confused, is Reiji's dad Esemori or not?
