its #1 on Netflix South Korea though and other countries :)
I saw a korean comment that said they prefer to watching it alone on Netflix as it isn’t a drama they want to watch with family. I was confused about it too because the episode highlight vids often reach number 1 on Naver TV and this drama tops lists in Korea (Good Data, Content Power Index, etc). So I guess that could be one of the reasons.
