Does anyone remember the very first season of Return of Superman? Back in 2013, KBS launched the show with the family of actor Jang Hyun Seong. Who knew that the show would grow to become so famous later on?

Jang Hyun Seong had two sons, Jun Woo and Jun Seo. Jun Woo, in particular, received much love for his adorable looks as a child.

He had fair and soft skin and huge eyes.

With his gentle and polite personality, viewers came to adore him!

However, fans of the show soon realized back in 2021 that their precious Jun Woo was soon to become a legal adult in South Korea. Given that Jun Woo was born in 2003, 2022 would be the year he turned 19. And now that it is 2024, he is now 20, celebrating his 21st birthday in July.

Although there have not been many updates of Jun Woo in 2021, back in 2020, fans caught a glimpse of him after a long 7 years off broadcast. As Jun Woo is a regular kid, after his family left Return of Superman in 2014, Jun Woo went incognito and returned to his regular life and studies. Needless to say, many were shocked to see his growth after a whopping 7 years. Here’s how he looked like on The House Detox back in late 2020.

He’s almost as tall as his father now! We can see that his younger brother, Jun Seo, has grown too.

When the topic was rehashed in 2021, everyone realized that time had flown by.

And while Jun Woo continues to stay out of the spotlight too much, his father talked about how he was doing, including a hilarious story about how he auditioned for the role as the Beauty for a high school rendition of Beauty and the Beast.

He does have a personal Instagram account and while he does not update it often, he has uploaded pictures with his father along with his band, Magnolia Cheers.

At the end of 2025, he shared a selection of pictures from 2025, including the conclusion of his military service.
