To be exact I'm looking for the more rare dramas with female leads that do the protecting or fight alongside male leads?
Not so much talking about personality in general, but more so their role as shown in the examples.

Example Scenarios: Female Bodyguard/Spy/Vampire/Superpowers
So far I think The King 2 Hearts, IRIS have a similar feel in terms of some of the female roles.

Thanks! =)
Female Bodyguard stories :
- Sweet Sweet Bodyguard (but there's not much bodyguard stuff so I actually wouldn't recommend it for strong female lead)
- Wild Romance (Also more of a romantic comedy than anything else but still she does her job.)

Spy stories :
- Call of the Country (undercover agents, the male mc is still very protective of her but she's the one taking risks)
- Myung Wol the Spy (Really funny)

Fantastic dramas :
- Bring it on, Ghost (she's a ghost helping an exorcist)
- Cheo Yong (a female student ghost helping a policeman)
- My Girlfriend is a Gumiho
- Psychometrer Eiji (she's a cop getting help from a student with superpowers)
- Raak Boon (the main character is a woman in possession of a cursed box)

Police dramas :
- 7th Grade Civil Servant
- H.I.T.
- When It's At Night
- You're Under Arrest

Other :
- Destined to Love You (she's an instructor in an army school)

( don't be deceived by the house selling plot because it's a great watch, give the first episode a try, the female lead is very different from the dramas I've watched so far and the drama itself has lots of refreshing new characters)

Gokusen
(she's a cool teacher, fighting for her students)
Oh! How could I forget Gokusen? Shame on me. I second that one.
Cruel City (Lee Jin Sook)
Age of Youth (Yoon Jin Myung, Yoo Eun Jae, Kang Yi Na)
Good Doctor (Cha Yoon Seo)
They're all Japanese :)
