Functional K-Drama families?

I'm looking for recommendations with a happy, functional family (bonus points if both parents are living). I really don't have any other criteria at the moment, I'm mostly curious if such a thing exists. I'm watching Ho Goo's Love and it made me realize that families like his where a) both parents are alive  b) are actually happy and not abusive in some way have been rare in the dramas I've watched. 

Try :

Playful Kiss 

Boss & Me (C-drama)

You're right, happy and functional families are rare
