SM Entertainment unveiled a short video on the trainee period of popular boy group EXO. The video, available on Twitter, shows the trainee days during which EXO members were going through tough practice sessions.

“I was a trainee for about six years,” said Suho, describing the difficulties he faced as a trainee. “I will never forget those moments.”

The video came as SM Town is set to screen “SMTown the Stage,” a documentary, in local theaters from Aug. 13-26.

The film is based on “SMTown Live World Tour IV in Osaka Special Edition,” which was held on July 25-26.
