Girl group SATURDAY is ready to "BBYONG" and captivate the public.

SATURDAY's third single, "IKYK," will be released on various music sites at 6 p.m. on Sept. 19.

The title "BByong" is an impressive song with its powerful track based on saxophone riffs and addictive strong melodies. In particular, choreographer Bae Wan-hee, who gave birth to Momoland's "BBoom BBoom" and "BAAM" choreography, will participate, adding a variety of point choreography, from easy-to-follow dance to propeller dance, to the fun of watching the stage.

Also, the music video for "BByong" is directed by Lee Sa-gang, director of "Jonibros" and emphasized SATURDAY's "pretty kid next to pretty girl" as well as photo-grapher Lee Soo-jin, who is famous for filming pictorials of many idol groups such as X1 and CIX and (girls).

Through this activity, SATURDAY plans to spread the global "BByong" trend with fresh charm and watery cutie bouncy that has never been shown before.

SATURDAY, which will feature five-person, five-color charms, will hold a fan showcase at Cheongdam Ilji Art Hall on Sept. 20 at 8 p.m., and applications will be available at the Hot Trace online mall and offline Gwanghwamun branch until 3 p.m. on Wednesday.
