Similarities because of the "New Service" (or Nandemo Suru would suit better) created within the department of Police, when in fact it's just a plain office where nobody wishes to be.

There are quite some similarities in both dramas like the fact that the younger woman has quite some temper while the older one always try to put a good face, not causing any troubles and such. In the Korean drama they are rivals due to the circumstances.
