After 400 cycles, 8482 "turns" of pain and suffering, it has been done. I have maximally traumatised this child. They physically cannot have worse coping mechanisms. 
If a normal MC spent 4 years drifting in and out of the void, this little girl has experienced 1600 years of torment. All before Harvard could introduce himself
How did I do this?
I noticed about few months ago that if you said no to Sheo back in the prologue and went back to the title screen, when you start a new game you would retain any stat changes. The first choice of the game changes some of your stats by 1%.
Of course to increase all your coping mechanisms to 100%, it would take an incredible number of cycles of the prologue, 400 to be exact. So I did that. Still there is no choice to increase the middle coping mechanism, it needs a different strategy.
Luckily, in our meeting with Harvard, we can pick the middle coping mechanism and decide to... taste our tongue, so to speak. This option instantly sends it to 100%, along with the choice to go back, keeping MC alive, but retaining their unhealthy coping mechanism.
Please don't do this yourself, at least not by hand. It took me over three hours. Also please don't patch this out, I very much like this feature. I wonder what that says about me.
Uhh, anyways, I love this game so much, I don't mind the glacial pacing, and the kid's reactions are so natural and saddening. Poor MC, hopefully they'll get healing eventually.
