At one of the last concerts, BTS sung DNA. But in the part about love, with Jungkook and Taehyung (you) singing right after the other, Jungkook came up to Taehyung and put a hand on his cheek, getting touchy as he sung with a bunny smile.

And at Taehyung's part, he did the same.

Jungkook smiled and sung his part with more emotion, making all the ARMY who ship Taekook go wild.
