My Tyrant Manager's Worst Nightmare

I was just a junior employee, a punching bag for a tyrant manager who made my life hell. She drove me out, broke me down, and left my family eating bread slices for dinner. Three months later, I walked back into that office as the new Chief of Staff, two levels above her. She thought she could crush me again. She has no idea who I really am, or the storm of vengeance I'm about to unleash. This isn't just a comeback; it's a corporate execution.
