May the muffins be forever in your favour.Chapter 32 (THE REAL ONE!) of "Letters to Cozy Glow" is here: "A Letter to the World's Most Famous Scholar" · 5:40am Apr 2nd, 2021
I got you. About 11 hours ago, I released the "final" chapter of "Letters to Cozy Glow" and announced that the story is finished. And while there was some scepticism at the beginning, most of you fell for it, either initially or because of my convincing comment responses. But it was all a prank to mark the day, so you are all officially April Foals of 2021 now! 
To clarify the joke itself, it was never about joking over suicide, as some of you understood it. The joke was merely to pretend that the story is over, while the suicide of Cozy Glow was just a means to an realistic "end" of the story that would look believable. Like I said, I don't joke about suicide. The inspiration for the suicide of Cozy came in part from some comments the story has gotten, which said that Cozy won't get better if she stays imprisoned in Tartarus. Will she get better down there, with the help of letter therapists? Not in the non-canon April Foals 2021 end, but in the real story? You have to follow and wait and see to find out.
So, let's get on to the new chapter, Chapter 32, the real one this time. Cozy Glow is on a letter quest to be convincing and act all nice and reformed..... But is she truly reformed or is it all part of the act for a big plan of hers? Loyal, recurring readers can already guess the answer on that question, everyone else might find one in the newest chapter. Or not, because Cozy Glow is really good at this.

P.S.: If you still want to relive the April Foals Day joke about "Letters to Cozy Glow", you can do that here:
Oh my Celestia you should be ashamed of yourself! *glares, the grins* OK, maybe that was a little funny... *bursts out laughing* Yeah, you got me. Oh goodness. And we all actually BELIEVED you!
I must admit, that might be the most twisted April Fool's jokes I've had played on me. But I see the funny side now you've explained yourself. You've outdone yourself, Fluttercheer.
Oh gosh
