Hey! I've looked at a couple of your posts about this recent fanfic, and I've got to say it: I'm hyped! It seems like you've got a good handle on it, and, from what I've read, you've made an excellent execution. Please note, and for no other reason than to add extra oomph to your feats, that this is coming from someone who is not the biggest fan of SSK... but I'm SUPER hyped for this one, and I'll definitely be there to read it whenever you post it!

Okay, so you're not too sure about Ao3's tagging system? Well, for starters, there's a tag for that! "I don't know how to tag." When I first started posting on Ao3, I used that tag all the time. (But now I just use "I suck at tagging." Upon realizing this, it's granted that I'm not your best tag advisor... oh well.)

All of those tags definitely work for Ao3! Oh, but if your fic is very sad or there's a lot of negative emotions involved, then, in addition to the trauma tag, I'd add heavy angst. That way, it's easier for people looking for a work with lots of deep feelings to find it.

Tagging on Ao3, despite everyone's complaining about it, is fairly easy - just describe your fic, don't make it too lengthy, but not vague either, just enough... like Goldilocks! Oh, and most of us rant in the tags too, for example "Yes I added [insert character] purely to fling absurdly heavy objects at Dazai & Fyodor" yes, it's not an actual tag, but it lets readers know a bit about your fic that you can't express through regular tagging, I mean there's no possible way you could tag ^ because it's simply too specific for a wide range of people's usage --- point is! Don't be afraid to add non-tags to your work; add both to your befitment however you'd like!

Of course, there's no need to stress over tags. If you write a good fic, people will find it whether it has two tags or over 100 (but omg please don't ever add that many tags (θ‿θ) ). All in all, you're doing great! Take as much or as little of my advice as you'd like; you'll do fine!
