Actress Yoon Seo Ah is earning praise for her performance in tvN’s weekend drama Bon Appétit, Your Majesty, where her on-screen partnership with YoonA adds warmth and dimension to the storyline.

Yoon Seo Ah plays Seo Gil Geum, a character gifted with an extraordinary sense of smell who becomes a reliable ally to YoonA’s chef Yeon Ji Young. The drama follows Ji Young as she time-slips into the Joseon era and meets tyrant Yi Heon, whose unmatched palate drives the survival-fantasy romance. Seo Gil Geum is one of the first people Ji Young encounters in the new era, helping her accept her circumstances and adapt to life in the unfamiliar setting.

The chemistry between Yoon Seo Ah and YoonA has been described as one of the show’s most engaging elements. Portraying an 18-year-old girl with a rustic accent and boundless curiosity, Yoon Seo Ah quickly bonds with YoonA’s character, their sisterly dynamic enhancing the drama’s emotional pull. Her scenes—whether marveling at Ji Young’s first dish or delivering lighthearted comedic moments—have added both humor and heart.

Off-screen, their camaraderie continues. After the premiere, Yoon Seo Ah affectionately posted on social media, calling herself YoonA’s “clingy little sister,” giving fans a glimpse of the genuine closeness between the two actresses.

As the series progresses, Seo Gil Geum evolves from comic relief into a pivotal figure. Beyond serving as Ji Young’s interpreter of Joseon’s world, she also amplifies the drama’s culinary themes by reacting with curiosity and awe to each cooking scene, embodying the audience’s perspective. Recent episodes revealed her hidden skills when she stepped in to cook during a high-stakes contest against Ming Dynasty chefs, delivering an unexpected twist and showcasing her growth.

Yoon Seo Ah’s nuanced acting, blending innocence, humor, and determination, highlights her strength in period dramas and female-driven narratives. Since her 2016 debut, she has expanded her range through roles in Today’s Webtoon, Nevertheless, and Goodbye Earth, with standout performances in historical dramas like Bloody Heart and The Tale of Lady Ok. These experiences have shaped her portrayal of Seo Gil Geum, a layered and endearing character whose journey resonates with viewers.

Cultural critic Kim Sung Soo noted, “Yoon Seo Ah fills the drama’s spaces with warmth, humor, and surprises, balancing the intensity of other characters. Her womance with YoonA not only enriches the story but also broadens its emotional spectrum beyond romance.”
