Cha Eun-woo’s younger brother has become a hot topic online after making a brief appearance on the tvN talk show “You Quiz on the Block.”

According to online community posts, the singer-actor’s sibling appeared in the June 11 episode of the show, which featured Oh Chang-gyu, a former semiconductor company vice president who became an intern in a real-life version of the movie “The Intern.”

In one scene, which lasted about four seconds, several company employees were shown walking together. Viewers quickly noticed a man who was later identified as Cha’s brother, drawing attention for his striking resemblance to the star.

Cha himself had already spoken about his brother during a May 2024 appearance on “You Quiz.” At the time, he revealed a photo of his sibling, then a journalism student in China, and shared a playful story: “My brother once said he wanted to beat me at something. But I never let him win.”

His family also drew attention in December 2024, when both his mother and brother briefly appeared on the tvN show “Rented in Finland.”

With both brothers now having appeared on “You Quiz,” their strikingly similar looks are once again in the spotlight.
