hey i did all that but never got the skill now she works on weekends. did all the dialogue concentration is 10. nothing ded the library did all of it. but the inner voice never gave me the skill. i downloaded the game 3 different times. 3 different new games. what do i doIf you haven<t found it yet, this is how you get it.
you need to meet the sad girl (Maria) by the park bench. Sit next to her and go through the dialogue. (you'll get Concentration + 2)
Go back the next day around 14h00 (afternoon) and talk to her a second time (you'll get another Concentration + 2). Your inner voice will then tell you how to use the new magical power.
enjoy.
