The Yellow One: Butterfly Protocol
Marcel is just tired.
That’s what he tells himself.
The headaches. The silence. The feeling that something is… waiting.
But when the yellow butterflies start appearing — and no one else seems to notice — reality begins to crack.
Something is watching him.
Studying him.
Preparing him.
And when it’s ready…
It won’t just take his body.
It will take what’s inside.
