Lee Jae-jun
BIOGRAPHY
Lee Jae-jun (Korean: 이재준; born September 25, 1997) is a South Korean actor and singer signed to J-Win Entertainment. He plays Hyeon in The Lie We Lived In (2026).
He debuted in 2012 as a member of the six-member boy group C-CLOWN under Yedang Entertainment, performing under the stage name Maru. The group disbanded in October 2015. He went on to debut with TREI under Banana Culture Entertainment in 2017, and later with the duo JT & MARCUS under MLD Entertainment in 2021; the same year he competed on the survival show Extreme Debut: Wild Idol, finishing in the top five.
He has also worked as a television personality, appearing on variety programs including Mix Nine (2017), Weekly Idol and I Can See Your Voice, and fronting the YouTube content series Cityboy_Log from 2023. His acting credits include a supporting role in FC Soldout (2025) as Kay, before he was cast in The Lie We Lived In, released on Wavve in 2026.
In March 2025 he debuted with a third group, IN A MINUTE, under J-Win Entertainment, alongside members Kim Jun-tae and Kim Hyun-yeop.
No admissible source publishes his height, weight, blood type or education history.
BLGLFlix editorial view
He has debuted four separate times.
Lee Jae-jun, born 25 September 1997, plays Hyeon in The Lie We Lived In. He debuted in 2012 with C-CLOWN under the name Maru, again in 2017 with TREI, again in 2021 with the duo JT and MARCUS, and again in March 2025 with IN A MINUTE.
The Korean system produces this pattern and almost no other industry does. A group is a company product with a contract term attached, and when the term ends its members do not become former idols, they become available. Redebuting is the ordinary route back in, so one performer can accumulate more first days than most careers contain.
Thirteen years of that is a long time to keep starting. It also explains the shape of the acting: a supporting part in 2025 and another in 2026 is a slower entry than a headline casting, but survival shows and variety credits are what kept him on screen in between, and that is the work that makes the slower entry possible at all.
His height, weight, blood type and education are not on this page. Korean idol profiles routinely publish all four, and not one of the four is carried anywhere this site would cite, so those fields stay empty rather than borrow.
