9. She often watches documentaries to understand her characters better

In order to fully immerse herself in the headspace of the roles she plays, Sung Eun shares she often resorts to watching documentaries that feature people similar to her characters. “When I first approached [my character from Beyond Evil], I focused a lot on her mother’s disappearance. To be honest, that’s an incident I can’t even begin to imagine…” she explains in an interview with Esquire Korea. “So I searched a lot for documentaries regarding missing persons cases. Watching these documentaries made me realize that the pain and sadness I had imagined was nowhere close to the pain these families went through.” Additionally, Sung Eun took a similar approach to prepare for her character, Mi Rae, in Ten Months.
