The dog lover (Patreon)

For those who don't remember, Brooke Houts is a youtuber who destroyed her carreer a few years ago by accidentally posting a video in which she was hitting her dog. 

So this is a story in which a reality bender shows up at her place and tells her that this is not how you should treat your dog. Well obviously, he does more than just telling her, and Brook's life will never be the same after that.
