I'm afraid we don't have enough data to determine the creator. It might be someone who is really into a specific genre or fandom and decided to create this fanfic. There are so many fanfic writers out there, and without more context, it's impossible to point to a specific person.
Since we have no information about the specific fandom it might belong to, we can only guess. Maybe it's a fanfic where a character has some sort of special power related to blood and has to face a threat in the form of a worm - like creature. Or perhaps it's a more symbolic story where the 'blood' represents family ties or heritage and the 'worm' represents a corrupting influence that this heritage will eventually expose. But again, this is all speculation without further details.
The male protagonist accidentally turned into a bug, but he still wanted to retain his personality and thoughts, and find his sense of belonging in the process of mutation. One of the plots is that the male lead vomits blood and a worm when he takes a shower. It fits the plot hint you provided very well. I hope you like this fairy's recommendation. Muah ~😗
The male lead of the anime " Song of the Worm " was a freshwater fish called " Ray."
