1TEAM will unveil its new digital single "ULLAELI KKOLLAELI" and music video on various music sites at 6 p.m. on Aug. 4, and will showcase its first comeback stage through SBS MTV's "The Show."

1TEAM's new digital single "ULLALI KKOLLAELI," which will be released on August 4, is a hip-hop dance song that combines elements of rock with cute lyrics that seem to tease a friend who is sad about a breakup, and an addictive chorus that repeats "ULLALALI KKOLLAELI," which combines the unique voices of the five members and the atmosphere of the song to give bright energy.
