D-Business Entertainment‘s new girl group D-Unit made their debut performance with “I’m Missin’ You” today on Music Core.

This is their second live performance as they appeared on M!Countdown earlier this week.

Earlier this week D-Unit released both their music video and dance version video for their title track.

Instead of starting out slow and releasing a single or mini album to test their popularity, the group released a full album for their debut. Their album “Welcome To Business” was released on August 2 and contains nine tracks.

Their group members are RAM (Jeon Wooram), Ujin (Jung Yoojin) and ZIN (Kwak Sujin). It was previously reported that RAM is the younger sister T-ara’s Boram. Ujin is a former trainee at YG while ZIN is the maknae and main vocalist.
