Found some more relatable DQ11 protag stuff off matomame.jp! Shy mode can kick off right in the prologue 0:

The text box approximately says ‘What if I started the conversation by misreading ‘Sumimasen’(Excuse me) as ‘Shyumimasen’, what should I do… …you couldn’t talk because you got shy!’

The fact that in shy mode the protag can just give up on talking and cover his face makes him extremely relatable

The text box approximately says ‘Hwah! I really can’t do it! This thing with talking is completely impossible! …You can’t talk because you became shy!’
