Alright, I just realized I never put out warnings for Jay's story. In the beginning, I will say it's 13+. But as we get further into the story, it will start getting closer to 18+.
So the next chapter will have some reference to Jay getting a period, just be aware. I probably will not outright say it, but it will be there.
If that or anything else 18+ makes you uncomfortable, I am sorry. But this story doesn't happen in the same timeframe in a sense, as the characters are all of age.
