Affiliate Marketing Secrets

So i have a niche/cult hobby(i know its weird in public eye but I LOVE IT) basically I’ve noticed 3 times throughout the year when I’m watching an anime on my laptop two mintues later I will hear my roomies mumble words like Japan Anime dumb stupid and other explicit words. I’m always wearing headphones but is there a way their screen peeking. One of them is an RA so maybe he has the powers to do that at the dorm. All i can say isn’t that an invasion of privacy. I love my hobby to death and want to be a voice actor but everytime i do a goofy voice in my room I feel like i will be talked about behind my back or something. The walls in the dorm aren’t thick either so they can probably hear me say an anime line

I started thinking about ideas for a book, I have written books before, but I was thinking more of a futuristic fantasy setting that would look really good in a manga, but I can’t draw for **** and I am thinking of just writing it as a book. Would that type of style of book be popular in the American market (No pictures, just words). The book would be about a boy who finds a magic pair of headphones, that he uses to help save either his world or another, and discovers the secrets of the headphones throughout the story.
