'싹쓰리' 데뷔 D-day 12부

유두래곤, 린다G, 비룡의 음악방송 데뷔날! 장난끼 가득한 리허설 현장! 리허설부터 티격태격.. 잘할 수 있을까? 8월 1일 토요일 오후 6시 30분 大공개!

The squabbling among the three members of SSAK3 doesn’t seem to stop even at the last practice before the debut. With Upset Rain on the verge of bursting into tears due to continuous bullying, they officially debut on Show! Music Core. When all fellow singers gather on the stage for the final score, the members of SSAK3 realize that they are on the list of first place candidates.
