I watched about 80 series in 2021. My favourites I’ve seen 3 or 4 times:
Hwarang
Boys Over Flowers
1st Coffee Prince Cafe
Are You A Human
Heirs
I am Not A Robot
The Empress Ki
Itaewon Class
The Tale Of Nokdu
Cinderella and the Four Knights
I only watched a handful of dramas in 2021, and the only one that broke me in such a good way was Lost (kdrama). I wish more kdramas will be produced in that beautiful 'show-not-tell' way. Alice in Borderland is also very wholesome (jdrama).
Mouse
Taxi Driver
D.P.
Move To Heaven
Mr. Queen
Chuno
Hahaha also not just 1 bc that is almost impossible....Top 8
