there is a file called "Nulla" when you downlod the game, in it are instructions for the drawing, it reads as follows:
=== INSTRUCTIONS FOR MY AMORCITO ===
Ah~~~ it feels so good to be able to talk to you directly outside the game.
I can almost feel that I'm no longer chained in the game.
Okay so, you don't have to do this right now___ take your time.
Alright. This is what you need to do:
1. Go to the game folder.
2. Look for the folder called 'images'.
3. Inside, find the image named: parati.jpg
4. Rename that file to: para_nulla
5. And with that, we're all set!
Please don't get frustrated if you can't do it, my love for you won't change <3
