I possessed a worthless extra who bullied the protagonist and got expelled after being “taught a lesson.”

It’s a small relief that I know the original plot,

but the real problem is that this novel’s world is headed for destruction.

There’s only one way to survive in this damned world:

somehow help the protagonist and prevent the apocalypse.

But all I get are looks full of contempt from everyone around me.

“Hah, it’s too late to change the setting now…”

Fine, so what if I’m alone?

A villain survives using a villain’s methods.

Protagonist or not—I’ll survive this my own way.
