Although Cha had his public debut as a K-pop idol, his acting career began before his music career. Cha had a little part in the movie “My Brilliant Life” before making his official ASTRO debut (2014). Although Cha’s true name is Lee Dong-min, he adopted the alias Cha Eun-woo after portraying the character in ASTRO’s pre-debut promotional web series “To Be Continued” (2015).

Cha will appear in the drama “Island” and the movie “Decibel” this year (working title).
