Cha Eun-woo’s Younger Brother Sends Internet Into Meltdown with “Face Genius” Visuals in 4-Second ‘You Quiz’ Appearance

The internet is abuzz after Cha Eun-woo’s younger brother made a brief but unforgettable appearance on tvN’s You Quiz on the Block (commonly known as ‘You Quiz’), stunning viewers with his striking resemblance to the beloved idol-actor.

Recently, online communities have been set alight with talk that Cha Eun-woo’s real-life younger brother appeared on a past episode of You Quiz on the Block. Though the episode originally aired on June 11, the brother’s cameo has only now come to fans’ attention, fueling a new wave of excitement.

The episode in question focused on Oh Chang-gyu, a real-life executive-turned-intern whose story mirrored the film The Intern. During the broadcast, there was a brief four-second scene showing several company employees walking together — and among them, eagle-eyed viewers spotted a man believed to be Cha Eun-woo’s younger brother.



Despite the blurry footage, fans couldn’t help but notice the uncanny resemblance: from his facial features to his physique and proportions, the mystery man looked almost identical to Cha Eun-woo, instantly capturing viewers’ attention.

As news of the cameo spread, netizens flooded comment sections with reactions like, “How did their parents raise two sons like that?”, “There’s another Cha Eun-woo in this world!”, “Those genes are incredible,” “They look exactly alike,” “How can someone that handsome be a regular person?” and “I’m jealous of his coworkers!” The overwhelming response showcased just how captivated the public was by the family’s visuals.



This isn’t the first time Cha Eun-woo’s brother has drawn attention. Back in May last year, Cha Eun-woo himself appeared as a guest on You Quiz on the Block, where he mentioned his younger brother and even shared a photo of him, causing quite a stir thanks to his brother’s good looks.

At the time of that broadcast, Cha Eun-woo’s brother was studying journalism and broadcasting in China. Cha Eun-woo shared a playful anecdote, saying, “My brother once told me he wants to beat me at least once. But I told him I’d never let him win!”

The family’s visuals made headlines again last December, when both Cha Eun-woo’s mother and brother briefly appeared on tvN’s Finland Guesthouse, further fueling fans’ fascination with the star’s genes.

Now, with both Cha Eun-woo and his brother making appearances on You Quiz on the Block, the siblings’ “face genius” visuals are once again in the spotlight, delighting fans and sparking conversations across the internet.
