SEE ALSO: Former SM trainee Hansol reportedly amazed the audience with a perfect stage on 'The Unit'

As it was reported prior to this week's episode, Hansol perfectly performed on the stage of 'The Unit'. On this particular day, he decided to cover Taemin's "Goodbye" and wowed the audience as well as the judges which resulted in him receiving a "super boot".

Afterward, Taemin praised as well as gave some advice to the former trainee, "Actually, Hansol was one of the back dancers for my concert in the past. Rather than seeing his full potential, I think we were able to see his passion more than anything else today. I really like your style and feel so I would like to you to improve more in those areas. That way, you can show us more of your professional side."
