The real irony is there is plenty of fanfiction that goes through more rigorous editing than some published fiction. So the difference in quality between fanfiction and “professional writing” is totally arbitrary and made up. Except that some things that are more expensive are worse.
I’ve translated the ones that aren’t in English! (at least the ones in the main photoset, my Chinese isn’t good and I’m too tired from doing those translations to sit and decipher some of the characters that are blurry haha sorry)
