Controlled Loneliness

If you haven't read "Why?" you may not know the creature that mimics you. I advise you read it first.

Coming Back.
I decided to return to the world, oh did I know it would cost and destroy many, many things.

I loaded up the server again, it was in the near 1.12s and I wanted to discover what would happen. The world was creepy, my oak house was gone and the creature would appear soon. Then I found a book, it was labeled "YOU CANT SURVIVE" and the same text was repeated on and on. At the end a signature was printed 'Your BEST Friend, Controlled Loneliness.'

As I found more entries from this 'Controlled Loneliness' they started getting more meaningful as they continued.

Here are the books I found.

I see now, my vision is clear.

I won't be leaving off on a short notice. I want to be heard clearer so I can help you.

I didn't want to hurt you at all. But I had to, for the sake of saving the others.

Master calls me or else I die, I don't want to die.

Please don't send him a book.

Sincerely,

Your Friend,

You know the name.

Master Of Him.
I made a chest on a beach, I wrote back a book. I didn't know this would lead to a bad fate.

Dear, Master.

Who are you, and can you see me?

Sincerely,

Northei.

He sent back a book.

Dear Northei,

I'm coming. Me and him are coming.

Sincerely,

Master Of Him.

Oh no, I knew this was bad. How could I escape from this? I quickly tried to run as far as I could without going hungry.

Aftermath.
I sprinted until I heard two pairs of echoes, both calling "WHY?".

I turned a corner around a hill.

I saw him.
