Lyrics

Come with me
Come with me
Tell me now, I
Should I stay
Let it all burn, yeah

Start from X
End with Y
Follow me, yeah
1+1
1+2
Fill the void, yeah

201 1321 5831
723 743 4913

879 875 2145
716 906 4156

Come with me
Come with me
Tell me now I
Should I stay
Let it all burn, yeah
Syllables
Syllables
Make it work, yeah
Start from X
End with Y
Follow me, yeah

An additional hint (1ST = 256BIT [BINARY], 2ND = 128BIT) got published later in Public Static Void.

Hidden Text

The last frame is extremely dim:

When the brightness is increased, two pieces of text can be seen:

The pieces of text are “I miss her” and “https://soundcloud.com/572943". You can read more about the SoundCloud profile on the dedicated page.

Solution

If you assign a zero to white neuro and a one to black neuro, and write down their sequence during the numbers part, you get 10100101101001011101001010101001. This is the decryption key.

Next, “1+1, 1+2, fill the void” hints at fibonacci numbers. Let’s write down fibonacci numbers and the song’s numbers side by side:

• 0 1 1 2 3 5 8 13 21 34 55 89 144 233 377 610 987 1597
• 201 1321 5831, 723 743 4913, 879 875 2145, 716 906 4156

If you’re observant enough, you’ll notice that 201 1321 5831 is a shuffled version of 0 1 1 2 3 5 8 13 21.

If you’re even more observant, you will notice that 723 743 4913 is a shuffled version of (8 is omitted)9 144 233 377. And if you’re schizophrenic, you’ll realize that you have to remove the matching digit sequences from the fibonacci sequence:

0 1 1 2 3 5 8 13 21 34 55 89 144 233 377 610 987 1597 2584 4181 6765 10946 17711 28657 ...
^ ^ ^ ^ ^ ^ ^ ^^ ^^        ^ ^^^ ^^^ ^^^      ^^ ^^^^ ^^^^    ^ ^^^^ ^^^^^
2 0 1 1 3 2 1 58 31        7 237 434 913      87 9875 2145    7 1690 64156

Which leaves you with 3455861094181771128657…, and if you take the first 16 digits, i.e. 128 bits, you get 3455861094181771, which is coincidentally the encryption key we’re looking for.

Finally, there’s a Malbolge program embedded in the decoded text. After running it, we get the final piece of the puzzle:

Answer

First AES:

I don’t want to become an engineer. I feel so exhausted… three more years just to waste away?? It’s almost exam season and I don’t know how prepared I’ll be. I guess we’ll wait and see. My little sister hasn’t come home yet like she usually does, she’s not answering my calls either. It’s been days now… Too many things going on at once, these numbers, my brain hurts…

Second AES:

I think I found something that might work… I’ve been training her with my own consciousness… to fill in all the gaps. It’s the only thing that’s missing. I’m sure it’ll work! My roommate thinks I’m crazy, mixing together two people’s consciousness??? But I’m out of options, I don’t know what else to do… I’ve already been through enough. It’s almost- hold on…

Malbolge:

is that someone knocking on the door??
