Aww, thank you! I really appreciate that :) I'm glad you're enjoying the game, and I hope you continue to enjoy everything I have planned for Act Three!
As for the Quiet Girl, that's on purpose. MC even comments on how odd it is (and if you try to do naughty things with the class at Max Authority, she reacts even odder). Quiet Girl mysteries, plus the mystery of the Sword Girl, will be revealed in Act Three (provided you max out Authority before doing the Act Two finale) :)
