OK. First of all....

First of all, none of us know the conclusion of the story yet. Skimming through the raws, it looks like the white hair psycho chick has some obsession with our fmc- no normal girl has that kind of strange obsession, and the guy that will appear later on doesn't look too sane either.

So we have one asocial loner fmc, and we have two psychos in waiting through the story. From the looks of the current story, the two main girl is indeed the focus, the conflict will always involve them in some way. And seeing how christianity and "sin" is perhaps the theme of this story, there is more likely chances of this being a very yandere-ish GL. That's not a bad recipe for a thrilling kind of femslash story.

And since the story has not reached an endgame yet, I for one am looking forward to this psychological GL.
