A second cover from Cha Eun Woo fans will remember

This is not Cha’s first KPop Demon Hunters moment in the spotlight. Recently, he performed Saja Boys, a fictional group from Netflix's animated film, hit track MyLittleSodaPop, during ASTRO’s concert, delighting fans with his vocal range and stage presence. Now, with Free, he shows his versatility once again, this time in a collaborative setting that has now left fans emotional, as it might be his last official performance before he enlists in the South Korean military.



Cha Eun Woo is scheduled to enlist on July 28, 2025, for his mandatory service in the Republic of Korea Army’s military band. He officially applied and cleared the interview process in May and was accepted by the Military Manpower Administration to serve as a musician in the band.

He will undergo basic training before joining the band. To avoid crowding or safety issues, the enlistment location and time are being kept private, and no public event will be held. In recent days he debuted a short haircut on social media, a symbolic readiness for military life, and fans responded with emotional messages.


Beyond music, Cha Eun Woo has established himself as a leading actor in Korean dramas. He made his acting debut in My Brilliant Life in 2014 and rose to fame with roles in hit series like Gangnam Beauty (2018), Rookie Historian Goo Hae‑ryung (2019), True Beauty (2020–21), Island (2022–23), A Good Day to Be a Dog (2023–24) and Wonderful World (2024). In 2024, he debuted as a solo singer with his EP Entity, featuring the single Stay, and later released ASTRO’s surprise track Circles.
