A different narrator may have given this a shine. I was shocked to learn halfway through that this guy is a motivational speaker. He was so flat and had no personality. He mentions several times that other people tell him he's funny and I was like ... really? Do they?
Have a personality. Have more than one speaking tone. Maybe don't speak about the "friendzone" with absolutely no sense of irony or self awareness.
Maybe everything up until chapter 31. In some ways this was just bizarre. I almost felt like I was listening to an alien describe what it would be like to learn the ways of humans.
How are you going to write a book with literally the exact plot of High Fidelity (published 1995, adapted into a feature film in 2000) and never once mention High Fidelity?
