Residual Lives [JJK various x GN! reader]

Do you ever feel like you've done this before? Not in the way of simple familiarity, but something deeper-something wrong. Like the air shifts around you, just slightly, as if reality itself is adjusting to your presence. Like you've stepped into a life that isn't entirely yours.

What if you have?

There are other versions of you. Not metaphors, not possibilities-real, breathing, thinking versions. Some only a fraction different. Others unrecognizable. And sometimes, without warning, you slip. Maybe it's a moment, a breath, a blink too long. Maybe it's longer than that. And when you return-if you return-you aren't sure if you've always been here, or if something else has been wearing your skin in your absence.

Do you ever notice the things that don't add up? A memory that feels borrowed. A scar you don't remember getting. The way people look at you like you've changed when you swear you haven't.

How many times have you shifted?
How many lives have you stolen? How many of you have been lost along the way?

You are not one.

You are many.

And in the end, you are nothing but the residue of all the selves that came before.
