Read all books?
In the early parts of the game, reading books raised your personality stats; Charm, Knowledge, Guts, Kindness and Proficiency
Each had a certain role to play later on in the game.
I:E if your kindness was high enough, you couldn't pursue meganekko past a certain point etc etc
Once in new game+ your stats are already max, so you don't spend time reading books etc
