Best Male Performances in a Kdrama

These are not my favorite actors or even favorite characters; these are what I think are the best acting performances I've seen by an actor in a Kdrama. The dramas these performances were in are as follows, in order: Signal; Tree w Deep Roots; Misaeng; It's Okay, That's Love; Cruel City; A Man's Story; Coffee Prince; Six Flying Dragons; Scarlet Heart: Ryeo.
