Before they appeared, Yoo Jae Suk expressed worry about whether they would actually come together, asking, "Is this going to work?" Kangta said, "I purposely didn't contact them. I wanted them to personally make a decision after receiving the offer." Following Kangta, Tony An joined, and then Moon Hee Jun, Lee Jae Won, and Jang Woo Hyuk appeared on the stage they originally debuted.
As the group gathered together, each member teared up. Moon Hee Jun recalled their last concert, where he promised fans, "H.O.T will never disband." He shared, "I've heard a lot about that from fans as well. I asked them to protect us, so I feel even more sorry for it. Because I said those words, I felt really guilty."
