Most of the names will not be strange to you since all of them blossom ever since their childhood acting days. These actors are my personal favorite but of course, there are more child actors that have grow up and taking lead roles in dramas and movies as well.
Lee Se Young

The actress that first caught my eyes not as a child actor but her role as the cute zombie in Korean Odyssey and randomly watched the movie, When I Turned Nine where she is a girl from Seoul moving into a village school.
She is currently leading the role in Memorist as a high IQ senior inspector working in the police forced and known to be the best profiler.
Yoo Seung Ho

Acting since he was 7 (international age) the actor is someone I know that grew up in front of the audiences’ eyes but I did not catch his drama until Memorist. Really good acting skill and with his partner, Lee Se Young, both of them made me creep out while watching the horror thriller.
Yeo Jin Goo

Always acting the young version of the main leads and finally got to shine as the main lead in Orange Marmalade in a vampire-human romance with AOA’s Seolhyun. He then shine brighter with his General Manager role, Goo Chan Sung in Hotel Del Luna last year.
Kim Hyang Gi

Start to really notice this actress after I chance upon her interview as a child on Star King, and she was adorable. After that, I caught up with her drama and movie with one more still on my ‘To Watch’ list, Innocent Witness.
Kim Sae Ron

This actress caught my eyes while I’m watching Leverage and later discover she was a child actress and I’ve watched her movie with Kim Hyang Gi, Snowy Road. With Kim Sae Ron breaking through her child actor image with Leverage, participating in popular web drama Love Playlist 4, really looking forward to more of her dramas and projects in the future.
Kim Yoo Jung

The cutest eunuch! Totally fall for her charm after watching Love in the Moonlight. Probably watched her acting as the young version of the main role in both Dong Yi and Moon Embracing the Sun. Coincidentally, all of the drama mentioned are historical dramas.
Do you have your bias as well?
