Kang Dong-won and Song Hye-kyo starred in the 2014 “My Brilliant Life” as married couple Mi-ra and Dae-soo. The child actor who played their son Ah-reum was Jo Sung-mok, but in fact, there existed another son. It was in the scene where Ah-reum imagined his healthy appearance.
Surprisingly, the actor who performed Healthy Ah-reum was Cha Eun-woo, who is currently a famous and handsome singer-actor.
It’s such a precious scene since you can see Cha Eun-woo’s rookie days. He also appeared in a swimming scene and the scene where he takes a walk with Chae Seo-jin, who played Seo-ha in her imagination.
Cha Eun-woo is still mentioned as “Kang Dong-won and Song Hye-kyo’s son” in many articles introducing him.
