Both dramas are set in the world of TV broadcasting and about the life and stresses of show-runners, directors, actors and producers. The world we live in is probably one of the more realistic Korean dramas I have seen. It may not be everyone's cup of tea, there is neither comedy nor a love triangle, but I would recommend it.

Both dramas have a strong focus on the entertainment world, its good and bad sides, as well as human relationships. Both stories have a slice of life vibe.
