On September 21, Tango Music announced the addition of U-KISS members Alexander and Eli to the company's artist lineup. 

The two will be joining fellow U-KISS members Soohyun, Kiseop, and Hoon who are already signed with Tango Music, hinting at the group's continued promotions under the agency. 

Earlier this year, 6 members of U-KISS including Soohyun, Kiseop, Hoon, Eli, Alexander, and AJ gathered for a special mini album, 'Play List', commemorating the group's 15th anniversary since debut. The group then held a successful 15th anniversary concert in Japan, reaffirming their dedication to the group and to their fans. 

According to Tango Music, AJ also plans to remain within reach for future group activities, based on his affection toward U-KISS.
