Now, for the neutral ending—as far as I know (I'm not sure if it's actually the neutral ending)—you have to perform specific actions, almost like there's a "love" bar, if you can even call it that... I'll post the step-by-step guide below, hehe.
Neutral Ending Guide:
* Main objective: Finish the game with fewer than 10 Affinity points and fewer than 10 Fear points. Do not max out either bar.
* The apple on the counter: Choose "Leave it where it is".
* The bathroom mirror: Choose "Check the mirror".
* Leaving the bathroom: Choose "Leave the bathroom without looking back".
* Mold apparition: Choose "Scream".
* Breakfast: Choose "Sit in silence".
* Morning dialogue: Choose "Good morning".
* Keys: Choose "Carefully take the keys".
* Clothes: Choose "Grab the shirt/cardigan".
* Market (Phone): Choose "Call someone".
* Leaving the market: Choose "Go".
• After leaving the market: Choose "Return" (Return home).
• Upon arriving home: Select "Take a bath".
And then he won't bother you while you're sleeping soundly, heh... heh?
