On December 23, rookie boy group OnlyOneOf's agency 8D Entertainment released an official statement, confirming member Mill's return to group promotions. 

Back in November of this year, 8D Entertainment raised curiosity from fans after announcing OnlyOneOf member Mill's sudden hiatus from all activities. The reason given was that Mill had violated a group rule, but the agency did not clarify what this violated group rule was. 

Now, on December 23, 8D Entertainment announced that Mill would be resuming his group promotions starting on this day. Furthermore, the agency also shared a handwritten letter of apology addressed to fans in light of his recent hiatus. 

Meanwhile, OnlyOneOf's Mill plans on greeting fans with his very own 'V Live' broadcast later on this day.
