Kpop Group Debuts of 2019

7: MustB

MustB originally released a music video for their debut title track 'I Want U' on the 1st of December, a couple of days after member Chibin had announced he had left the group. The CEO of their company, Must M Entertainment, then posted about the release of the music video on his Instagram, only tagging four out of the seven members. Not tagging Chibin makes sense, as he was no longer part of the group, but what happened to the other two is unclear. No articles were released at the time and the social media the group had had not been used yet, leaving people wondering about their names and what was going on.

Then MustB opened up their Makestar debut support project, revealing the official profiles for the seven members currently in the group, on the same day as they released the mv teaser for their new version of 'I Want U', including the new line-up. The second version of the music video was released the 21st of January on their own channel, whihc is the same day as the group held their debut showcase. 

On the 30th of January, the music video was released on Stone Music Entertainment, at the same time the single was released, marking their official debut.
