Awards history

Before the Emmy, her most significant prior recognition came from the Baeksang Arts Awards 2022, where she won Best New Actress – Film for her leading role in Young Adult Matters (2020). She also received nominations at the Blue Dragon Film Awards 2021 and the APAN Star Awards 2022.

Outstanding Guest Actress recognition

The Television Academy officially recorded her acceptance at the 2022 Creative Arts Emmy Awards. The win placed her in rare company among international guest performers recognized by American television’s most prestigious body.

Can Lee Yoo-mi speak Mongolian?

Lee Yoo-mi has publicly demonstrated a Mongolian accent, most notably in a TikTok video that circulated widely among fans. However, her broader language proficiencies beyond Korean have not been formally documented in biographical sources.

Language skills

Korean is her established working language, consistent with her South Korean upbringing. The demonstrated accent suggests either personal linguistic background or researched performance skill, though she has not clarified which in published interviews.

Mongolian accent in media

The viral TikTok clip showed her speaking with what appeared to be a Mongolian dialect, generating positive engagement from viewers familiar with the accent. This remains her most visible public display of language versatility outside Korean.

Lee Yoo-mi Squid Game role

Lee Yoo-mi portrayed Ji-yeong, also identified as Player 240, in Netflix’s Squid Game Season 1 (2021). Her character appeared in a limited number of scenes but delivered one of the series’ most emotionally resonant moments before her character’s fate was sealed.

Player 240 Ji-yeong

Ji-yeong was a contestant in the deadly tournament who formed a brief but meaningful connection with another player. Her character’s arc concluded within the first half of the season, yet the emotional weight of her scenes generated disproportionate audience reaction relative to her screen time.

Impact on career

The role sparked an immediate surge: her Instagram following grew from approximately 40,000 to over 6.5 million following Squid Game’s debut, according to Wikipedia. Industry recognition followed, including the Emmy nomination and eventual win in 2022.

Lee Yoo-mi movies and TV shows

Lee Yoo-mi’s filmography spans over a decade, including roles in over 12 cinema films and 14 dramas before her Netflix breakout. Her post-Squid Game appearances have been notably frequent, with leading roles in several major series.

All of Us Are Dead

In 2022, she played Lee Na-yeon in the Netflix zombie series All of Us Are Dead. Her character represented a sharp tonal contrast to her Squid Game persona — a villainous, self-centered rich student rather than a sympathetic contestant — demonstrating range across genre.

New drama As You Stood By

Her most recent verified credit is the Netflix series As You Stood By (2025), in which she starred as Jo Hui-su. This places her among the most consistently active Korean actresses across the streaming platform’s original programming.

Summary

Lee Yoo-mi’s story is a case study in how streaming-era television has compressed the timeline between supporting actor and internationally recognized star. A character who appeared for fewer scenes than most ensemble cast members generated the most-watched drama series in Netflix history, an Emmy win, and a following measured in the millions. For Korean actors pursuing international recognition, the precedent is clear: quality of defining moment outweighs quantity of screen time. Her next projects will determine whether the Emmy represents a peak or a launching point.
