The Baeksang award gives awards movies, TV and others, but the TV award is the most prestigious and is considered to be Korea's Emmy's.
Every year, the competition is fierce..
I will only do actresses
2019
Kim Hyeja - Veteran actress - Ultimate Grand Prize (higher than Best Actress)
Yum Jungah - Best Actress
Kim Seohyung, both from Sky Castle
Kim Taeri (mostly a movie actress), for Mr Sunshine
Lee Jieun (the Singer - yes I get to mention here at here too) for My Mister
2020
Kim Heeae, for the World of the Married - Best Actress
Kim Hyesoo
Kong Hyojin
Son Yejin
Lee Jieun
2021
Kim Soyeon, for Penthouse series - Best Actress
Shin Hyesun
Um Jiwon
Kim Sohyun
Each year, only one under-30 actress was nominated, and Lee Jieun (two times) and Kim Sohyun were shubbed
But, in 2022,
there is no competition
against Lee Seyoung of Red Sleeve (one cannot win twice for the same show which rules out Kim Soyeon and others in Penthouse)
While she is 31 in Korean age she was born in late 1992 so she would be 29 years and change in western reckoning.
Lee Jieun failed twice
Kim Sohyun failed once
but
Lee Seyoung snags the Best Actress award in one shot.
