Hi, I'm looking for movie or drama recommendations with a female protagonist who is an accomplished professional (detective, lawyer, businesswoman, politician etc), who lost someone important to her in suspicious circumstances related to her job, and is determined to unveil the truth/get revenge with her own hands.
No overt romance or FL sacrificing herself for the sake of revenge.
It can be a sub-plot if it's a tv series. Thank you!
(ETA Japanese, Korean or Mandarin, please.)
