[talk] Madonna came to BTS's waiting room and shook their hands.

I'm not talking about Madonna, but I think it's an overseas performance.

Madonna came to BTS's waiting room in person, shook their hands, and even taught them the Cha Cha Cha dance.

BTS is proving their world class.

Madonna feels embarrassed because she passed by without seeing Jungkook extending his hand.

He came back to Jungkook again, shook his hand, and left. That's really awesome.
