So I've been working on my original story, and I am confident that the rough animation for the steamy scenes will be done this month. After that, there are only a few scenes for the epilogue. I've decided to move the supposed ending for episode one to episode two as its intro, since I imagine that ep 2 will be much shorter than the first. Another change that I've recently decided on is the time period for ep 1. The setting for ep 1 will now take place during The Great Plague, Ep 2 will take place during the early 1900s, and ep 3 and 4 will occur during the modern age.
And finally, I think I'll settle with this title.
