After the resounding success of his first solo career debut with SEVEN, Jungkook continued to join hands with US-UK rapper Jack Harlow for his next solo work "3D". The interaction between Jungkook and Jack Harlow excited fans because it created a musical product that was pleasing to the ears.

Not only that, the two's adorable friendship in real life also makes fans excited. Recently, a video behind the scenes of filming the "3D" MV became viral because of Jungkook's reaction after learning Jack's real age. Fans shared their sympathy with his reaction upon learning this.

Below is the reaction that fans can expect when Jungkook knows Jack Harlow's age:

At the end of September, Jungkook returned with the second single in his solo career and met fans' great expectations. By collaborating with US-UK rapper Jack Harlow, "3D" brings international-style sound, catchy meloďïệs and of course, the interaction between the two artists is the most attractive topic to the auďïệnce. 

Right from the release of the "3D" MV teaser, Jack Harlow and Jungkook have had close interactions on social networks such as sharing photos taken together. In particular, there was a photo posted by Jungkook and Jack Harlow that caused a stir as it showed that Jack Harlow even gave his iconic necklace to Jungkook to wear.

The iconic Kentucky necklace that really shines on Jungkook's neck originally belonged to Jack Harlow. According to Hypebeast, the piece was made to honor GRAMMY Award-winning αmєrícαn singer-songwriter and producer Static Major, who, like Jack Harlow, was born and raised in Louisville, Kentucky and often wore his own Kentucky necklace.

While netizens enjoyed the flashy necklace, some fans noted that Jungkook wearing this meaningful necklace was a sign of respect from the Louisville rapper. Even if they only wear them for photos or as gifts, fans can still see the close friendship and respect that the two have for each other.

But that's not all the wonderful interactions between the two were recorded. Recently, a video posted on Bangtan TV titled "정국 (Jung Kook) '3D (feat. Jack Harlow)’ MV Shoot Sketch", recording Jungkook's reaction when asking Jack Harlow's age.

Most fans know that Jack Harlow was born in 1998 while Jungkook was born in 1997. But in terms of appearance, they don't have much difference, Jungkook even looks a bit younger. Therefore, many people sometimes mistakenly believe that Jack Harlow is older than Jungkook.

Even Jungkook had such a misunderstanding until he learned that Jack Harlow was only 25 years old, one year younger than him. Jungkook was surprised to hear about this and he even laughed when he was enlightened about Jack's real age. He even repeated: "Jack's 25. I'm 26. I was shocked".

After seeing Jungkook's reaction, many fans also a̾s̾sured him that they had similar thoughts. While some others laughed at his adorable reaction:
