But but he rides a motorcycle in his underwear only, what a Chad!So the author has the MC pursuing his mother aggressively despite her fighting for her marriage and it being incest, but rejecting his sister because it is incest. He suddenly also feels it is amoral for his sister to want have sex with him after drinking. His solution : take her to bars and get her drunk twice a week, and then sleep with her when she has a high alcohol tolerance. The story "no more money" is initially about a guy willing to do anything because he is broke- but of course he now tells his boss he doesn't care about money, turns money down, and rejects starting his own business.
This guy is so wonderfully awful, I think other causes of conflict can be found more in character.
EDIT: found a typo, while jogging MC says mother instead of landlady
