I stumbled on this drama one day and I'm so grateful I did.
The story was engaging and never got stale. A nice mystery murder story with twists, turns, emotions, and backstory galore.
The acting was superb by both of the male leads. The cast as a whole was really fabulous to be honest.
Lee Dong-sik was such a captivating character. His expressions alone had the ability to squeeze my heart throughout the series.
Yeo Jin-goo was kind of the king of character development in my opinion.
The chemistry between the characters was captivating and really brought the series up to the top spot for me.
I could really go on about this series forever, but I would hate to spoil it for anyone.
Rewatch value: I've rewatched it three times so far. ???
