Rapper Ja Mezz (real name Kim Seong-hee, 32) admits to drug use and disbands his hip-hop label GRDL. However, he denied the allegations of dating assault.

On December 28th, GRDL's released an announcement on their Instagram page saying, "We are deeply aware of the responsibility related to Ja Mezz, the musician and representative of our company, which has been controversial recently, and as of this day, we are announcing the dissolution of GRDL.” They also said, "Ja Mezz will return as an individual and will not evade if there is something he is responsible for."

Ja Mezz also opened up about the recent suspicions on his SNS that day. He said, "I sincerely apologize for causing a stir. I am grateful and sorry to my family, friends, and GRDL family who waited for my position," he said. However, he explained, "The texts and photos shared by A in the chat room on the 19th are false facts that contains edited provocative words and images." However, regarding the picture of the broken windshield of the car released by A, he admitted that it was true that he did it.

In addition, he admitted to the use of drugs, specifically cannabis and LSD, "I have done marijuana and LSD in the past. If there is any legal punishment for this, I will accept it."
