STRONG+HARDWORKING WOMAN in kdrama

 KingARMY:

Then you can try night light, it has 2 awesome female leads

Also secret forest, but idk if she fits the hardworking category. Same for Signal(korean vs.), awesome female lead.

You can try Mystery Queen but idk if would call her physically strong or hardworking.... but she is awesome....., another example would be Mrs Cop series. Awesome female leads and stories for both seasons.

i totally agree with Signal, thx for your rec, i will try it
