So, so far, on this story, I've gotten Ian, Allison, and Tina's good endings (and thus completed their story arcs), and I'm completely bewildered on what path is required to get Olivia's good ending. I've tried basically everything I can think of to get it. Haven't done the True ending, yet, since I'm heeding the advice of the story description. Any help, Killa?
(Also, may I say, so far the game is exceptional. I'll reserve judgment on it as a whole, until I finish all the story arcs.)
