Both dramas depict the same period of time in history.

Pledge of Allegiance comes from the pov of an imperial police while The Imperial Age covers the pov of Zhu Di (the dude who ends up with the throne in the end).

Both FLs are stuck in rather toxic relationships unknowingly until they encounter their respective MLs

Both have similar vibes and well-developed characters. Both are centered around the imperial family.

Both dramas are about:
- Office romance
- Office dynamics
- Multiple couples
- Family business
