Why does it feel so unfamiliar and fascinating to see Jin's older brother on TV?

When I saw my older brother on a variety show on YouTube, I felt really unfamiliar yet fascinated for a moment.
It's also kind of funny how the whole atmosphere is settled with just one word: that the younger brother is BTS's Jin.

Many other celebrities appeared on Jung Jun-ha's YouTube channel, and seeing him naturally blend in with them felt more realistic.
It was more impressive that they looked like people actually traveling together, rather than just like a celebrity's family.

I liked that the introduction as the person in charge of grilling the meat was funny for some reason, but it also made the atmosphere feel comfortable.
They didn't seem like they were trying to stand out just because they were a celebrity's family; in fact, I found their quiet demeanor even more likable.

Maybe it's because Jin himself is such a global star, but it is fascinating how just his appearance on TV generates such a lot of buzz.
But on the other hand, it also feels like we live in an era where we’ve become somewhat accustomed to families being naturally exposed to the public like this.
What I remember most about the appearance was just that it came across comfortably without any exaggeration overall.
