The idol group visited Beijing for its “2016 BTS Live Asia Tour” on Saturday and the group’s members had performed in heavy suits in the sweltering weather.

The concert had to be temporarily halted as Rap Monster grew breathless due to the heat. A medical team attended to him while the group’s remaining six members carried on with the concert.

Rap Monster said on social media on Sunday, “I am sorry to cause you all trouble, and especially to my Chinese fans for not being able to show my best. I am a lot better now!”

“2016 BTS Live Asia Tour” is the K-pop band’s first concert in Beijing and all 15,000 tickets for it were sold out, according to its agency.
