Kain of the new boy group ARGON talked about his past as a BTS backup dancer. 

On March 11, ARGON held the showcase for their 1st single 'Master Key.' Member Kain shared how he started dreaming of becoming an idol, and said, "In the past, I was active as a dancer and I got to make my debut as I wondered what it would be like if the cheers and shouts I hear on stage was for me."

Kain revealed he stood on stage with BTS, and said, "I gained stage experience by going on a world tour with BTS sunbaenim. I started dreaming of becoming a singer since then and I also got to spend a good time as a dancer. I was active as a dancer for 2-3 years."

He continued, "I believe BTS sunbaenims practice for about 16 hours a day. I need to follow how they're always working hard and doing their best, even at such a high position."
