Similarities:
- Oh Soo Jae (Why Her?) / Hwang Do hee (Queenmaker): capable women that go above and beyond for the company they work for and are considered the aces of the company.
- Both have revenge//seeking redemption arcs
- The Female leads have a long and complicated history//relationship with their bosses.
- There’s a suicide case that's blamed on the FLs
-They have unexpected turns and bomb truths


Differences:
- Why her? Is a law drama whereas Queenmaker is a political drama.
- Queenmaker has a sisterhood focus Why Her leans a little into noona romance but its main focus is Oh Soo Jae
-Why Her? feels, for me, darker and heavier.
