Everyone is intelligent/calculative incl the "dogs"

Drama where everyone is intelligent and tries to outsmart the other ones, meanwhile their supposidely loyal underdogs are just as calculative and intelligent as them and not brainlessly loyal to their masters, like in most dramas. 

Basically where neither the main protagonists or the villains are safe because their "friends" or "loyal" subordinates may betray them at any time in an attempt to take their position.
