She’s the new lead in Bridgerton Season 4 — Yerin plays Sophie Baek, the love interest of Benedict Bridgerton in the upcoming season of the hit Netflix series

She’s Australian with Korean heritage — born in Sydney and of South Korean descent, her casting brought a culturally meaningful name change for her character

Her character’s surname was changed to honor her heritage — Sophie’s original book name was Beckett; the show changed it to Baek to reflect Yerin’s background

Acting runs in her family — her grandmother, Son Sook, is a renowned Korean actress and radio host, and her parents met at acting school

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
