I played this before, but may have missed this, but I just played this all the way through from the start yesterday. I wonder if when Cassie had the code for Koko MKI stolen, she was looking for 1) Her "initial" code, which she thinks she created with the MC?, and 2) the key to making her AI working. Just a thought - as if she cannot get her AI to work, she can sue the pants off the MC to try to say she helped write some of the derivative code. That was why she probably make them start over when they started after high school, so no one can say their code was the same as the high school stuff. Just a plot point I am seeing.
