That is the fundamental error that you didn't understand and why its a futile effort (at least in my eyes
/ also no i'm not judging you i'm just saying the FACTS, also no i'm not toxic just trying to help, also no i'm not trying to start drama, also for the love of god i hope no morons will reply some brainrot stuff. Said all that just in case, bc despite trusting you doravg for not misunderstanding me, i fear the incoming random users. Usually 5+ good replies, 2+ morons or "smartass")
yaoi ISNT popular for SH readers
(also clarification, just in case there will be wordcherrypicking people, NOT to SAY they are hated but more "not appreciated" here.)
Not that its bad or that you shouldnt do yaoi. But that the audience for SH in particular....well it's not their cup of tea. Hence a "Sisyphus rock" difficulty level task.
You would have better chances, if you wrote in AO3 or fanfic.net
or this specialised (for women) websites full of female readers, where 9 series on 10 are female romance or yaoi stuff.
But sadly this last part, not sure it exist on western part of internet. I mean, there is danmei.com (not sure if .com but basically "danmei") for chinese internet. EVEN JP had a separate website for "female users" compared to syosetu / syosetu18 / nocturne.com, called (wait a second i search the old thread about it on NU forum....) "
https://mnlt.syosetu.com/" Syosetu MOONLIGHT.
Also not spurn on it (just possible theory), but another reason why "yaoi" is unpopular in SH (its just my guess, maybe i'm wrong)
is probably because NU for years now
had like 7 releases on 10 be yaoi stuff, on the main front page (that tell updates)
and well.....like some chinese novels told : its always pleasing to the
eyes seeing girl be with girls, even girls like that
Another factor you forgot. (again, i'm not criticizing you but just telling info)
Is that you picked : Hetalia
Hetalia is good. I don't care to be honest if good or bad.
But that SH....well it's not really mainstream well-known popular.
Its basically if someone would try to do a RWBY or a AVATAR or a POKEMON or a ARCANE or a DANGANRONPA fanfic on SH.
There are exceptions, but its mostly bc its smut and popular things. Danmachi (it looks very popular but in fact not really, the core fans would say it too). They can only exist on SH if its a R18 story where the MC get hestia. (can't someone do a Danmachi Loki ffs orz T_T)
Anyway i finished.
My recommendation, try posting somewhere where its more likely to succeed.
Though, seeing as you tried to write a crack story, i guess AO3 could work.
Especially with the number of yaoi stuff there, that make it look like its a fujoshi website or a non-2d-fanfic-website, despite welcoming everything.
