The label stated, "Seven O'clock's former member Vaan has decided to leave the group, and the team will regroup as 5-members with A-Day, Hyun, Younghoon, Junggyu, and Taeyoung. The label and the members tried to convince Vaan [to stay] numerous times, but ultimately, we decided to respect the individual's wishes to stop participating in the group's activities, and the team will be regrouping. It was not an easy decision for the members. We ask for your continuous support and attention toward Seven O'clock and Vaan." 

Seven O'clock, who debuted under Staro Entertainment in 2017, will now be managed under Forest Network. The group plans on picking up preparations for their comeback as a 5-member group, soon.
