this is kind of difficult to rate. On one hand the story got a great and interesting setting, and on the other the execution feels rushed and emotionless at point.
x scenes are well written, emotional interactions are not.
Honestly, I am nitpicking way too much on this an will probably continue reading this some time.

The thing that bothers me the most is that all human women he dates, without any explanation, are fine with just being FWBs with the MC. One girl had a crush on him for years.
