KDramas with outgoing/funny male lead?

I've seen a lot of great kdramas but i went through a phase where nothing seemed entertaining until i watched when the camellia blooms.  Although the male lead character wasn't brand new it was nice seeing more of the nice, outgoing, protective, male lead to the  female lead instead of being cold. Any recommendations for kind outgoing male leads similar to yong shik?

+1 for Flower boy next door, it's the first title that came to my mind. 

Revolutionary love

Protect the boss

I hear your voice (noona romance)

Heart to heart (he doesn't have a bright personality but he very quickly warms to her for the whole drama): this one depicts pretty realistic feelings from the ML.

It's Okay that's love, pretty much the same, though the story and characters are different.
