In the series My Incomplete Life or Miseang, there is a character who is outstanding as a sales manager to our lead character Jang Geu-Rae. He shows up in the Kdrama Memory as an attorney. He is outstanding, and so is this series (on Ep. 8 right now). Of course, good actors show up repeatedly in dramas. In this one, fans of Heard it Through the Grapevine will recognize the teacher that was brought in to help. He is one of my favorites. After your favorites show up, you start feeling like "this is going to be a good one!"
For those of you who are fans of mature dramas, you have hit the jackpot with this one. No spoilers, ok, so here is what is outstanding about this one. First, you don't get the compelling part of what drives this thing right away, like in any good story. Then, you start to. By then, you are hooked. Check out Memory on Viki. You won't be disappointed.
