and before you ask why recommend these 3 websites is because ao3 is full of amazing quality bnha fanfics i know that because that where find most of my bnha fanfics reads and in spacebattles they have very friendly communities and including sufficent velocity compare to web-novel

i Think you should use a different website for this because if this happening for what is probably something miner mention like writing word Korean which does not make sense because i do not remember anything like that and even if you did that little to extreme for Webnovel to do that because i seen fictions and fanfics like that here but they were of horrible of quality. and if you decide to use a different website i do not recommend watt-pad it full of half finish story what i recommend ao3, spacebattles, sufficient velocity if you do switch.
