On September 19 KST, Mystic Story Entertainment announced that K-pop group Billlie is set to make a comeback in October with five of its members. The group's members, Siyoon, Sheon, Tsuki, Haram, and Haruna, will be actively participating in the group’s activities. The quintet will be busying themselves with vibrant activities both domestically and on an international scale. Notably, Sua and Suhyeon will not be participating in this comeback. 

This comeback sees Billlie returning to the limelight approximately seven months after the release of their 4th mini-album, 'The Billage of Perception: Chapter Three,' in March. Notably, Billlie shattered their own initial Chodong sales records with this four-part album and secured their first music show trophy for their hit song "EUNOIA."

As all eyes are on Billlie's forthcoming comeback, the band has confirmed their return in the following month, and are fully engaged in preparing for their much-anticipated performance and promotional activities.
