he trained in South Korea — Yerin moved to Seoul as a teen to study at the Kaywon High School of Arts before returning to Australia for further training at NIDA
She has appeared in major TV shows before Bridgerton — including Halo (produced by Steven Spielberg) and other series like Bad Behaviour
Her audition journey was intense — she submitted her Bridgerton audition within 24 hours, worrying about her British accent, and filmed a chemistry read over Zoom while jet-lagged in Korea
She champions representation and diversity — Yerin speaks openly about the importance of inclusive storytelling and visibility for actors of diverse backgrounds
She’s creatively multifaceted — beyond acting, she’s enjoyed dancing in music videos, theatre roles (like Lord of the Flies), and enjoys painting, music and yoga in her personal time
She’s battled imposter syndrome — despite her success, Yerin has said the pressure of being a visible Asian lead has made her reflect on representation, identity, and self-belief in the industry
