Protective Male Lead

Any Korean dramas with protective, almost jealous and obsessive, male leads towards the female lead? What I'm really looking for is the protective, I-want-to-take-care-of-you element.

Something like Master's Sun - not the Ghost element, but how he always looks out for her.

It's not Korean, but one I liked a lot was Boss and Me.
I've also watched Healer, and Cruel City, and Girl Who Sees Scents.

You've probably seen all of these, but hard time checking your list on my phone:
cruel romance
hotel king
yong pal
i hear your voice
man of honor ( both make characters were obsessed with her)

My love eun dong is better than what it sounds. They 'dance round' each other because she doesn't know who he is due to memory loss. Don't want to say much more as it will contain spoilers but its a very sweet love story worth a watch. 

@Nezumi - I'm watching My Lovely Girl right now. I like the romance between the leads and that he wants to take away all her troubles, but I'm on episode two and every time I have an aww moment, I spoil it by remembering he's only this way because he's taking responsibility for his late girlfriends's younger sister. It's like he's an older brother she has a crush on. Will he ever get over himself and her sister and focus on her?

@SSKF oh nice! (I forgot to check your currently watching list so I didn't notice sorry ^^') and yes, he does! so don't worry too much about that :)

Ho-goo's Love (Fool"s Love) - Main character protective beyond belief.  Uee is in the drama and worth watching

Goodbye Mr. Black. It's not yet finished though. The lead is a total protector. :)
