Actress Yerin Ha will play the love interest of Luke Thompson’s Benedict Bridgerton in Season 4 of Netflix period drama series Bridgerton, the streamer announced on Wednesday, sharing a short video on Instagram.

The Australian actress will play a character named Sophie Baek. She will join recurring cast members Ruth Gemmell, Claudia Jessie, Golda Rosheuvel, Nicola Coughlan and Luke Newton in Season 4 of the show.

“OMG the newest member of the ton...Yerin Ha as Sophie in Bridgerton Season 4,” wrote the official handle of Netflix.

The streaming platform had previously announced that the fourth season of the Shondaland show will focus on the love story of the second eldest Bridgerton sibling, Benedict.

Season 4 of the Chris Van Dusen-created series will be based on Julia Quinn’s 2001 novel An Offer from a Gentleman, the third book in the eponymous eight-book series. In the novel, Benedict falls in love with Sophie Beckett, an earl’s daughter who has been relegated to the role of a servant by her disdainful stepmother.

According to a recent press communique on Netflix’s companion site Tudum, Sophie’s surname has been changed to Baek in the show out of respect for Ha’s Korean culture.

“As a victim of tragic events, Sophie has been forced to spend much of her life working for the most demanding employer in the ton. But the resourceful Sophie always finds a way to persevere through her circumstances — circumstances which will drastically change after she disguises herself to attend Violet Bridgerton’s masquerade ball and meets Benedict,” reads the official synopsis of Bridgerton Season 4 on Tudum.

Thompson’s Benedict spent Seasons 1 and 2 of the Regency-era series pursuing his passion for art. Season 3 saw him indulging in a steamy romance with Lady Tilley Arnold (Hannah New). He spent most of the last season tangled in bedsheets with his new lovers, including Lady Arnold’s friend Paul Suarez (Lucas Aurelio).

Bridgerton Season 1 explored the love story between Daphne (Phoebe Dynevor) and her husband Simon (Regé-Jean Page), while Season 2 revolved around the budding romance between Viscount Anthony Bridgerton and Kate Sharma. Season 3, led by Penelope Featherington (Nicola Coughlan) and Colin Bridgerton (Luke Newton), followed a friends-to-lovers theme.

The fourth season of Bridgerton, whose storyline seems to be a re-telling of the Cinderella tale, will reportedly hit the streamer in 2026.
