On Tuesday, November 4, it was reported that BTS' Jungkook's daily livestreams of his Kancho Biscuit unboxing have led to the snack's shortage in South Korea.

So far, his attempts to find his name on the snack have been unsuccessful, and the idol has continuously been holding livestreams, determined to find the same.

After the recent report on the Kancho biscuit shortage in South Korea, netizens soon realized that several other ARMYs and fans have also been purchasing the snack to indulge in the unboxing along with Jungkook. They also found it quite hilarious that the idol had already stocked up on several boxes of the Kancho in anticipation that it might undergo a shortage or get sold out.
