Queenmaker is about Hwang Dohee (Kim Hee Ae), the Corporate Strategy Team Director in Eunsung Group who is the fixer for the chaebol family who owns Eunsung, who ends up becoming the Campaign Manager to make Oh Kyung Sook (Moon Sori) the Mayor of Seoul, against Eunsung's chosen candidate.
I haven't watched a k-drama in a long time (Netflix subscription going to waste), but finally decided I was in the mood for one, and picked Queenmaker cos Kim Hee Ae my queen is in it. Been a fan ever since the sublime Secret Love Affair. I've mostly seen Moon Sori in smaller parts like The Handmaiden and Little Forest, but I know she's got an impressive filmography as well.
