Who Is Yerin Ha? Meet the Korean Actress Starring in "Bridgerton" Season 4

Netflix has finally dropped the first teaser for Bridgerton Season 4, and it’s already shaping up to be one of the show’s most romantic chapters yet. Think a masked-ball meet-cute and a Cinderella-like love story, told in classic Bridgerton fashion. We can't wait!

At the center of it all is Sophie Baek and her long-anticipated romance with Benedict Bridgerton. Breathing life into the role is Yerin Ha, an actress whose breakout moment has been quietly earned.

Here’s what to know about Yerin Ha, the woman leading Bridgerton’s next chapter.

Born on January 16, 1998, Yerin is 27 years old—and a Capricorn, which feels fitting given her career trajectory. Known for patience and discipline, Capricorns tend to play the long game. While Bridgerton marks her biggest role to date, Yerin’s rise hasn’t been a fast-track fairytale. It’s been deliberate and steady, built on consistent work rather than overnight attention.

Before stepping into Regency romance, Yerin previously appeared in Halo, the big-budget sci-fi adaptation that put her in front of a global audience. She’s also been part of critically minded television like Troppo and Bad Behaviour.

Yerin Ha was born and raised in Sydney to South Korean parents, and she has spoken openly about how her Korean heritage informs her sense of identity—both personally and professionally. In past interviews, she’s reflected on navigating the industry as someone who doesn’t fit a single cultural box, noting that representation matters most when it feels organic. She’s also noted how Bridgerton’s choice to adapt her character’s surname to “Baek” acknowledges that heritage in a way that feels natural rather than tokenistic.

In Julia Quinn’s novels, Sophie—then known as Sophie Beckett—is one of the series’ most complex heroines: illegitimate, raised on the margins, and constantly navigating questions of belonging, visibility, and class. Her story with Benedict Bridgerton hinges on disguise and social divide, making her both a romantic figure and a deeply pragmatic one.

Bridgerton’s decision to reintroduce her as Sophie Baek builds on that foundation. By grounding the character in a more culturally specific identity, the show gives Sophie’s outsider status additional emotional weight. It also aligns with Bridgerton’s broader approach to inclusive storytelling while remaining faithful to the emotional core of the book character.

Yerin's performances are grounded in craft. She trained formally in acting in Australia, including at the National Institute of Dramatic Art (NIDA), where she focused on understanding why she wanted to be an actor as much as how to perform, describing the experience as a period of “getting to know more about myself as an artist” and discovering that there is no single correct way to approach a role.
