Older leads, romantic/passionate but not dark

I'm hoping to find something where both leads are older, like 35+, but there's still lots of tension and passion as they fall in love - I don't necessarily mean I need steamy scenes (though that's welcome too!) just not the "gentle mature romance your grandma watches" that often comes with older leads. BUT, I don't want something full of affairs and unhappy people and a depressing ending. I hope I'm making sense! Basically, I want the same formula of popular k-dramas, just with leads that happen to be older. Thanks!

The Good Wife

Go Back Couple (One of my all time favourites)

Mask (A little old but this is an amazing drama)

Enjoy =)
