LU:KUS (루커스; known as L.A.U from 2016 to 2019) is a three-member boy group currently under JWK Entertainment.
They were formed in 2013 by Box Media but were shortly re-located to PAN Entertainment and officially debuted on July 4, 2014 with the single "So Into U". The group left PAN in 2016 and changed their name to L.A.U due to their previous agency holding the rights to the name. They reverted back to their original name in 2019.
On March 7, 2020, Haewon announced that he would be retiring from being an idol.
