Chicago typewriter. This is one of the many k-dramas I have watched but one of my favorites as well and I rarely leave a review unless it's worth to recommend. I got hooked from the first to the last episode. There are so many feelings that you could feel and lessons to learn from watching this drama. Just watch this drama so you will experience those as much as I don't want to spoil others who haven't given this marvelous piece a try.
From the casting to cinematography to the plot, just the overall story is amazing.
