The general content of the letter:

Dear Mr. Zero,

By the time you open this letter,

you will stand somewhere beyond my reach—

in a moment I have not yet known,

in a world I can only imagine.

Have you unraveled the questions I could not answer?

Have you broken free from the invisible chains that bound us?

Or have you found solace in the silence,

in the space between existence and nothingness?

No matter where you are,

or who you have become—

you are both the beginning and the end.

And perhaps, in this endless cycle of time,

I am writing not to the future,

but to myself, forever waiting.

Best wishes,

Yourself from the past.
