You might first notice that I did not rate this show highly in the re-watch category as I think I will take a long time to be able to watch it again, not the least because I doubt I will forget it for quite some time. Due to the platform I was able to watch this with family across the globe. It was unanimous !! Each of us rate this drama highly. I don't think I will add anything to the wonderful reviews written earlier as they describe the show so eloquently.
There are many Korean dramas which are not star driven but a tour de force of all performers and this is particularly true of this cast. This brings into focus the value of all relationships , familial, marital, friendship, work.....
My advice within this review is do NOT binge watch this show. It can take too long to recover from some individual episodes. The strength of the cast and script has resulted in scenes played with subtlety are still capable of packing a heavy punch. I highly recommend watching this drama but with someone so that the phone calls/discussions add to the experience. Stay safe all.
