The past pictures of B2st, Big Bang, 2AM, and 2PM were revealed.

KBS2 'Win, Win' aired on the 21st invited B2st as guest members, who talked about their separate dreams in separate agencies. When they first debuted, people criticized them as the "recycled group", but they said because of those dark days, "today's B2st exists."

During this time, past pictures filled up the screen. Picturs of their young, boyish days were shown, not only of the B2st members but also of the members of Big Bang, 2AM, 2PM, etc.

Their looks were tacky and their skills were not as developed as now, but their innocence brought smiles to everyone.
