I'm a big fan of Korean Drama and I know a couple of actors that made their debut last year including those that have been in the industry earlier than that but finally got to blow up in 2021.

As for debutant, I give it to Jung Ho-Yeon

Remember her?

Heheh... She is the lady that escaped from North Korea in Squid Game. Very interesting character.

This is her first ever movie/tv series. I'm sure that we will see her get into more projects this year.
