B2ST made a guest appearance on the October 20 installment of KBS 2TV's 'Hello'  where Yoseob relayed a sweet message to fellow member Hyunseung during the 'video message' portion.

It was brought up that a previous time the boys were on the show (back on August 27, 2012), Yoseob had created a heartfelt moment by tearfully showing his gratitude towards Kikwang for all the help during his difficult training period.

This time, Yoseob wanted to relay a message to another member.  He said, "Hyunseung, it has already been five years since we debuted.  I'm not sure you remember.  Just like how Kikwang saved me, I saved you," making everybody burst into laughter.  It looks like he wants some thanks this time around!  

He continued, "When you were overly anxious auditioning here and there, I was the one who contacted you and found places for you to audition.  I wish for the next five, fifty years, we will be together as B2ST."
