Baek Dong-hyun

BIOGRAPHY

Baek Dong-hyun (Korean: 백동현; born October 13, 1995) is a South Korean actor. He plays Choi Mu-geon in The Lie We Lived In (2026).

He was born in Seoul. His earliest tracked screen credit is a supporting part as a Korean patient in the 2023 production BEEF. He went on to play Secretary Kim in the 2024 drama Marry YOU, and appeared in Sexy Marriage as Yoo Tae-mu and in The Lie We Lived In, both released in 2026. A cross-referenced Korean-language wiki entry additionally credits him with an earlier 2018 musical-theater debut and extensive later stage work, but as this is not corroborated by a second independent source it is noted here rather than asserted as fact.

No admissible source publishes his talent agency or education history. Two sources give conflicting height figures (178 cm and 180 cm) and neither could be corroborated by a matching second source, so height, weight and blood type are left blank per house policy requiring two independent sources in agreement for physical measurements.

BLGLFlix editorial view

His first tracked credit is an unnamed patient in an American series.

Baek Dong-hyun (백동현), born 13 October 1995 in Seoul, appears in the 2023 production BEEF as a Korean patient, then as Secretary Kim in Marry YOU in 2024, and in 2026 in The Lie We Lived In as Choi Mu-geon.

American productions with Korean characters now cast a great deal of small work out of Korea and out of Korean diaspora communities, and those parts turn up in Korean actors’ filmographies as a first line. It is a route that did not exist in this shape ten years ago, and it means a career can begin in a language and an industry that is not the one it will end up in.

An unnamed role is also a specific kind of first credit. There is no character to research and nothing to say about the performance, so a database records the fact of it and moves on.

One unconfirmed source additionally claims a 2018 stage credit for him. It is noted on this page and is not entered into the record, because a single source is a lead and not a fact.

Date of birth, home city and both spellings of his name are on the page. Representation, schooling and any social account remain unconfirmed and therefore unwritten.
