Cube Entertainment's special duo has released a batch of fresh concept images.

One born in 1998, Pentagon's Wooseok, and the other in 2001, Lai Kuan Lin, this new unit has come up with a debut album '9801' as Cube Entertainment's close brothers. These funky conceptual photos reveal the playfulness of these idol boys, looking like real brothers who are similar yet both unique!

Starting from March 4, the duo will release individual MV teasers, as well as the audio snippet and more. Stay tuned until the full release of the album, set to take place on March 11!
