has anyone else ever had a fanfic that just... haunts them? like it's been months and maybe even years since you read it, but it just lingers with you and you can never truly leave behind the imprint it made on you? and maybe it's just a single line, one sentence that you can't shake off, that takes up residence in your mind and stays there, feeding into your psyche and subtly influencing your brainspace and maybe even your writing or other works?
