i know i haven’t watch so many kdrama / series but as for me this one is a super high level drama i need and i want many like this. I like this kind of action and mystery movie but the reason i can definitely recommend this one for everyone is because of the story line and the cast holds each other tight. It served really well, full of chill but every episode makes me want to know what is the next story. i watch this drama in one go nonstop from every episodes, yet still can and want to rewatch it. Standing applause for the idea and result they give us for this masterpiece. once again i would like to say i hope i can see many dramas like this
