Ji-young Yoo

SunHee Seo (Korean: 서선희; born January 1, 1999), known professionally as Ji-young Yoo (Korean: 유지영), is an American actress. She made her first appearance in the 2021 Netflix comedy-drama film *Moxie*, credited under her birth name. That same year, she adopted the stage name Ji-Young Yoo, composed of Korean syllables she felt would be easier for English speakers to pronounce. She also voiced Zoey in the 2025 animated Netflix film *KPop Demon Hunters*.

In 2023, Yoo won the Best Performance in a U.S. Narrative Feature award at the Tribeca Festival. She left her degree program at the University of Southern California to film the 2024 Amazon Prime Video original miniseries *Expats*, for which she received a nomination for Outstanding Performance in a Limited Series at the Gotham Awards. In 2025, she portrayed Megan, one of the main characters in *Until Dawn*, a horror film set in the same universe as the 2015 video game of the same name. The film received generally mixed reviews, though several critics praised Yoo's character and performance.
