What We Know About Heo Nam-joon’s Twin Brother
Here is what is known about Heo Nam-joon’s twin brother as of September 2026.
Has Heo Nam-joon’s Twin Brother’s Job Been Revealed?
As for his younger brother’s job, there are some reports claiming that he works at a café, but this information does not appear to have been officially confirmed.
At present, there has been no official announcement regarding his younger brother’s occupation.
It is said that his younger brother asked Heo Nam-joon not to make information about him public, and Heo Nam-joon appears to be careful to respect that request.
Heo Nam-joon and His Twin Brother: Their Personalities and Childhood Stories
Heo Nam-joon has shared that when he was young, he sometimes wore his younger brother’s hand-me-downs. Apparently, his younger brother grew faster than he did, so the clothes ended up being passed down to Heo Nam-joon instead.
Interestingly, his younger brother did not call Heo Nam-joon by his name, a nickname, or even a cute pet name. He simply called him “Ya!”
In Korean, “ya” is a casual way of calling out to someone, similar to saying “Hey!” in English.
Even though that was how he usually addressed his older brother, things changed whenever they visited their grandparents’ house. Their grandmother, who was strict about family hierarchy, reportedly told him, “Call him your older brother.”
But his younger brother disliked calling Heo Nam-joon “older brother” so much that he apparently went the entire day without calling him anything at all. 🤣
Maybe that is just one of those classic brother moments!
It also seems that during their school years, Heo Nam-joon’s younger brother may have been even more popular than Heo Nam-joon himself.

Heo Nam-joon also appears to call his nephew “Heo-keu-rong” (허크롱). Unfortunately, I could not confirm the exact meaning of the nickname.
