When mentioning Jungkook, people will immediately think of a young and omnipotent idol. At the age of 26, Jungkook has achieved many achievements that are hard to imagine and owns million-dollar net worth.

But about 10 years ago when he first debuted, Jungkook was still a teenager entering Kpop world. When looking back at the immature images of Jungkook in the early days, many people wonder why Bang Si Hyuk at that time let him debut so early?

On a recent online community forum, netizens discussed how young BTS' Jungkook really was when he debuted with the rest of BTS. The post written: "How did you come up with the idea of debuting such a cute and small kid? Mr. Bang Si Hyuk, I am so glad that you decided to have Jungkook debut as a part of BTS (I really mean to say that I am so frickin' grateful)."

Do you remember how Jungkook was when he was a trainee and just debuted with BTS? You will surely nostalgic for little Jungkook with the pictures attached to that post below:

Indeed, the images of Jungkook when he first debuted with BTS carry the innocence and bewilderment of a young boy. He's so cute that anyone looking at his big, sparkling eyes will feel soft.

18-year-old Jungkook has a white face, big round eyes that sparkle as if he wants to see the whole world. But even though Jungkook was only 15, 16 years old at that time, he was called "Golden Maknae" by RM. It's not a random nickname.

The reason RM gave Jungkook this name is because he can do everything from singing, dancing, rapping and even his looks. Not only that, Jungkook has many different talents. Until now, Jungkook still shows that the nickname RM gave him is not wrong.

It is also said that although that year, Jungkook was just a boy who looked innocent, but inside he was a teenager with strong determination to become a top idol. Perhaps, because of seeing the growth and enthusiasm in Jungkook, Bang PD let Jungkook debut with BTS. And 10 years later, he achieved his dream and proved to Bang PD that his choice was not false.

Here are some netizens' comments when recalling the image of Jungkook when he first debuted with BTS:

- "The hyung (means 'older brother' in Korean) line was much older, so they couldn't wait until Jungkook turned 20."

- "He sings well so he's the main vocal, he dances well so he's the center in BTS's performances, but his face is also good looking. He's a rare all-round idol."

- "At the age of 15, Jungkook had to go to Seoul to raise Jin"

- "Can a person be this lovable? I started to really like Jungkook...I will love him forever..."

- "Wow, Bang Si Hyuk must be super proud ; That young kid grew up and can sing and dance, and became a world star..."
