I wrote up an introduction of the series here.

And here is chapter 4! More things happen! Not much I can post here because a lot of the story’s only just getting started and anything I’d say would be a spoiler.
Anyhow more character and plot development! Enjoy, everyone.

Again, this story has themes of infidelity, rape, suicide, gender inequality, blackmail, and murder. So be aware before reading.
