So, I realised that I might be recommending several stories by one particular author. This is cool and all, but I decided that it might be better if I made a post where I put in the links to several author's profiles. These particular authors are those that I personally really like, and I would very much like to recommend all their stories. 

So, here's the list of authors!

Here's a blog that is available to all. It's a TaeNy blog and contains many stories from well known TaeNy authors.

3981stories

theninthtrack

LYRCat

This is another blog of SNSD stories. The ones here aren't all TaeNy, so you'll get a good mix of other Soshi pairings.

I don't read quite as many EXO fanfics as I do SNSD, so I don't have that very many authors to recommend. I'll go by the little bit I've read and recommend 2 authors here.

kloh-ay

(She writes various pairings, mostly Kray and Baekyeol.)

purpleskies

(I haven't read all of the stories, but Revolution was amazing)

KoalaCass

(Mostly oneshots, recommended by kloh-ay)

This list is by no means exhaustive.. There are loads more out there, I just haven't named them all.. D: 

Do check out 3-00am's Iron Maiden.. Wonderful story
