On May 30, a press conference for Mnet's new music variety show 'The Call' was held, and TAEIL was one of the singers who attended the event.
'The Call' is a music variety show in which some top singers in Korea collaborate with other singers to produce a song together.

TAEIL said, "When I asked Jong-kook what I should do for the project, he gave me a healthy drink and asked me to come to his gym."
The following words by TAEIL made everyone at the press conference burst into laughter.
He said, "About a week ago, I went to see him at the gym for the first time, and I honestly thought I was going to die."

In fact, this was recently broadcast on SBS' variety show 'My Little Old Boy' where Hwang Min Hyun and Ha Sung Woon from another boy group Wanna One suffered from extreme pain carrying out some of Kim Jong-kook's workout routines.
