BTS’s Jungkook kept his promise at the age of 15 to always willing to tie the shoelaces and open the water bottle cap for the oldest member Jin

The brotherhood between Jin & Jungkook makes ARMYs extremely touched.

Despite the age difference, BTS’s Jin – Jungkook duo are a compatible pair at making jokes and teasing the rest of the members. Longtime Army probably still remember Jungkook’s famous joke: “I left Busan and came to Seoul at the age of 15 to raise Jin hyung.”

In the Permission To Dance On Stage concert taking place in Las Vegas, the maknae proved that the old saying is absolutely true when showing extreme concern for the eldest member Jin. Fans have many times spotted the moment Jungkook helped Jin, specifically when he saw his brother struggling to open a water bottle, Jungkook came and opened at once. The maknae even didn’t hesitate to bend down to tie Jin’s shoelaces. Their brotherhood is truly touching!
