any good crime/espionage/mystery/military/war romance dramas

Criteria:

- no dumb or annoying FL

- Chinese, korean or taiwanese

- 2000- now

- good ending or open ending

- a good amount of romance, doesn't have to be main focus

- good chemistry between leads

- it would be great if ML could fight and has brains as well as the FL

Dramas I've watched and liked:

Love Me If You Dare

When a Snail Falls in Love

K2

Healer

Vagabond

The Listener

Never Say Never

My Roommate is a Detective

Detective L

Battle of Changsha

A Journey to Meet Love

Flower of Evil

Age of Legends

City Hunter

A Murderous Affair in Horizon Tower

I'm open to historical and modern dramas.

Maybe Man to Man - FL doesn't fight, though.

 Czakhareina:

• Arsenal Military Academy
• Descendants of the sun
• Rookie agent rogue
• Under the Power
• Time between Dog and wolf
• Decoded
• Mystic Nine
• Sweety Spy
• The crown Princess - this one is a thai drama, but definitely fit all your criteria. 
•  the main lead had a good ending, the secondary couple sadly  has tragic end
  • King2hearts
  • Crash Landing Into You - FL is abit spoiled

Thank you! I'll check them out.

 AH :

• Lost Love in Times
• Come and Hug Me 
• Hello Monster - Romance isn't the central focus.
• The Masked Lover - A bit lighter with some comedy. 

The FL isn't entirely likeable at first, but she grows and all your other criteria are met:

• +1 Crash Landing on You
• I Hear Your Voice
• W
• Suspicious Partner

Thank you!
