hello, 

i'm looking for dramas that are about couples in their 40s 

I can suggest a few K-dramas featuring couples in their 40's

The World of the Married

Misty

Sky Castle - this one has a mix aged cast featuring parents (in their 40's) and their kids (late teens). Both older and younger cast share the same amount of screen time. 

Flower of Evil - not quite in their 40s but close enough. 

Five Enough - a widower with two young children and a divorcee with three

The miracle we met

penthouse (kind of messy though)

my love from another star

Maybe The greatest love and The master's sun. I am not sure how old leads are, but they are "older", 30+.

Among ongoing dramas, Emipre of Law is pretty good enough.

  • When my love blooms
  • Remarriage and desires
  • Second to last love
