I love this. I love that they eat together. Good friends wait for their friends to eat together.
I do this too which some people think is strange. Sharing a meal together with friends brings you together. It really does! There's a friend I only hang out with like twice or three times a year. When we hang out we always have a blast!
The fact that BTS does this means they are good friends. I would love to have all of them as my friends!
