Actors you'd like to see in the same Drama

There's a topic already "Dream OTP" which is about romantic couplings - but it got me thinking, what groups of actors would you like to see together not necessarily romantically - and in what kinds of settings?

I really enjoyed the three FL's in Search:WWW - what other actors and actresses do you think would be interesting to see side by side on-screen?

Two of my favourite actresses are Park Bo Young and Kim So Hyun and I have thought they might be good together as older/younger sisters - the age gap bringing some sparks and they have a different perspective on their lives - but fundamentally they're on the same side, they spa off on each other constantly but when the chips are down they're 100% there for each other.

Over to you :)

Woo Shik and Ki Yong! They were in The Boy Next Door and I'd love to see them play as brothers or friends. I just wanna see them in a full length drama

so ji sub and song seung heon...best buddies in real life, would like to see them in a drama together.
