this drama is soo underrated compared to other so-called "Big dramas", people who are not watching this are missing out so damn much I feel sorry for them. With very strong,interesting characters for BOTH male and female lead, the lead couple's AMAZING chemistry as well as OUTSTANDING acting performance, and the storyline that constantly keeps the viewer on edge while presenting the story of a man with his unique conditions and one of the best love stories, not to mention the excellent production and directing. After so many years I've became quite jaded with dramas and they could rarely hold my genuine interest towards the latter parts but this drama kept me excited and worked up with each new episode until the very end. I hope more people will discover this drama and appreciate it for the gem that it is like I enjoyed it, I feel so blessed to know that I was able to follow this drama while it was airing, every seconds of the swooning, tears and waiting for each episode was sooo worth it, I'm gonna miss it so much when it's over. Best Kdrama of 2020 for me.
