The ending of this is great. If you've got a job that pays decently but offers no satisfaction, the solution is a SIDE HUSTLE. Not a fulfilling hobby, not volunteering to improve your community, not even raising a family - all things that have provided satisfaction to countless people with well-paying-but-meh jobs over the history of office work. None of these things exist in the world of Usagi Sararīman, only MORE WORK.
