Very well produced k drama. There is no unnecessary plot (side stories), it is funny but at the same time it approaches a sensitive topic in a very good manner: job hunting, job opportunities for elderly and work environment in South Korea. Other problems, such as corruption and illicit activities are also part of the plot, but the way this drama handles it makes it easy to watch, one can really immerse oneself in the story. It is original and funny. Love, comedy, mystery, suspense, awareness of real life situations: this show has it all! I have watched MANY dramas and this one is no doubt one of my favourites.
