Their comeback activity begins in earnest through the release of the new album. On September 30th, each song including 'LIT', the title song, will be displayed in various music sites under the album named, 'FLY WITH US'. 

The '' LIT '' song is a combination of an oriental melody mixed with trap hip hop, a new attempt from the genre introduced by the previous songs. The music video of 'LIT' was directed by Zanybros Hong Won Ki and fused with the traditional Korean beauty. The blending of tradition and modernity adds magnificent yet visual richness, and maximizes the performance of the members, leaving a strong impression.

In this new mini-album, six songs were recorded including the titled song 'LIT', 'Intro: Fly Me to the Moon', 'Plastic Flower', 'Blue Sky ','Level Up ', and ' Stand By'.

Following the previous work, members Ravn and Lee do showcase their incredible talents having their names on all the composition songs except Track 6. The new album 'FLY WITH US' is the third of the 'US' series trilogy.

The US series covered three themes: the light of the Sun through 'Light Us', the time of the Earth through 'Raise Us', and the space of the Moon through 'FLY WITH US'. It is the theme that the light of the Sun goes through the time of the Earth and flies to the space of the Moon. 

ONEUS reveals their live power and energetic performances called "the genius of the stage" and their new title song 'LIT' is much anticipated to open a new chapter of their popularity.
