Hey, you can use AO3 in chrome, just go in chrome and search ao3 and you don't need to sing up or anything, you can read stories there without needing of signing up, but there's few stories where author put on restrictions like only ao3 account users can access to their story,
So after clicking on ao3, there'll be some terms and conditions, you have to click on agree and continue, then up there is search bar button, you can search author name to get the book you're looking for, or search the story with taekook in last.
And if you do not find that particular book then type the book name, for example if I'm searching the book, 'Ice like fire, taekook, milaskv, ao3' on Chrome search bar button then It'd show the story.
Hope this helps, you can ask me again if you didn't understand.
