I'm sorry, but without reading the actual fanfiction, it's hard to explain the plot. All we can assume from 'neio hurts max' is that there is some sort of conflict involving a character named Neio and Max.
Since we only have this short description 'neio hurts max stranger things fanfiction', we can only guess at the plot. Maybe Neio is an antagonist in the fanfic. He or she could be a new character with a vendetta against Max. It could start with Neio targeting Max for some unknown reason, and then the story might follow Max's struggle against Neio, with her friends from Stranger Things perhaps getting involved to help her.
Given just 'neio hurts max stranger things fanfiction', it's tough to detail the plot fully. However, generally speaking, in the Stranger Things universe, Max has faced many threats before. If Neio is the source of harm here, it could be that Neio has some connection to the Upside Down or some other dark force in the fan - created story. The plot might revolve around Max trying to figure out who Neio is and what their motives are, all while dealing with the physical and emotional pain that Neio is causing her. It could also involve the other main characters from Stranger Things, like Eleven or Mike, coming to Max's aid and trying to stop Neio together.
