One thing I can say about Kdramas is that more often than not, they manage to cast actors and actresses with great onscreen chemistry. Everytime I doubt a pairing, i end up wrong. This is one example.

The King's Affection was a joy to watch, in my opinion. I was watching this simultaneously with a Queen for Seven Days; and while the stories were different, QFSD was a bit dragging for me. TKA's cast did an amazing job of bringing their characters to life; even the secondary ones.

I cannot wait to see more of these actors in future projects
