Where do the hints lead me too? I am so confused. I put in the codes, they're telling me to go places, but I don't know where? Like, where's her favorite room? Which curtains? Etc.

For anyone wanting spoilers:

NOTE: You need to call each number before these interaction will appear. 

NOTE 2: If you are on the gutslut path you cannot do this ending.

I called one number, did the interaction, and then called the next number. I don't know if you can just call all numbers immediately one after the other and then go to the events one by one.

1. Curtain you need to check is in the dancing room, top right of the room.

2. Fave room is back in the old house upstairs, far right. Use the bed.

3. Another bed, in your bedroom-- the room you start the game in. 

4. After getting the basement key from the courtyard DO NOT GO IN to the basement. You must interact with the basement door and when asked a yes or no, pick no. Keep walking south.
