&TEAM released a highlight medley for its second Korean mini-album Mark on Me on September 2. Behind-the-scenes footage accompanies excerpts from six songs, including hip-hop Good Boy, retro-styled 러브장, pop R&B Accelerate and rock ballad Empty. The album adds a love story to the group’s wolf narrative, following change through acceptance by another person. It arrives September 8 at 6 p.m. KST, after the group’s first solo dome shows at Belluna Dome on September 5–6.
