While the fans were doing more research of YEONJUN, they discovered that he once came up on the stage of BTS V's solo performance as a backup dancer.
It was from V's stage of 'Singularity' at the '2018 KBS Song Festival' held on December 28.

Although his face was hidden behind a mask, YEONJUN's distinctive, deep gaze could not be hidden.
As there were four backup dancers in total, fans are going wild believing that the other three will also be announced as the members of TXT.
Meanwhile, Big Hit Entertainment has confirmed TXT to make its debut sometime this year.
