  1. Slight correction in the 0.9 section:

    You definitely have to at least talk to the STANDING guests to get the right scene with Rebecca. I just spoke to everyone, though. The Priest might be completely optional.

    • Need to talk to anyone: Talk to the priest, Talk to the guests who are standing, Talk to guest who’s sitting > Talk to the pianist > Evangelion

  2. I have a question about Carla, after the session with the doctor and we have the email session, I lose Carla’s path. I took every step in the guide but lost it anyway. Every possible combination also does not work, is there something I did wrong in the walkthrough or does following the walkthrough up to that point lose her path?

    • as referred from the walkthrough above when you wake up and go shirtless and approach her. At the scene where Carla’s washing the dishes and you approach her, you touch her a… and her heart meter increases.

      Touch A > Don’t push it (At the b… selection)

      The path continued on after the email session
