I forgot to mention this awhile ago, but Chapter 5 has been out for a month or so now. I was too preoccupied with Chapter 6 that I didn't realize until now.
I'm also sorry that it's taking some time for the next chapter to come out. Writing is fun, but holy crap is it hard. I'm trying to pace myself so I don't get burnout, but it's taking longer than I had initially expected.
