[소통] What challenge came before the sound source? lol

Apparently, the release date for the Boo Seok-soon Jeans soundtrack comeback is 6 PM today, but the Jeans Challenge has already come out?ㅎ

Is this a new way to promote a comeback? lol

I applaud the boldness of showing it in advance before the sound source is released.

By the way, even though I only heard it briefly, the dancing and the singing were so exciting that I think it'll go well this time tooㅎ
