A Transformed Girl's Self-Rescue Conquest

I'm a guy, not a girl. Ahem, I shouldn't use bad language.

In my previous life, a bunch of dumb high school classmates used, deceived, isolated, framed, and set me up. They really did a number on me.

And now this fairy has been reborn! Back two years, just before I met that bunch of dumb high school classmates.

So sh... this fairy should avoid them, or get even and ruin them?

Waiting for answers. It's pretty urgent.
