Singer Nicole of girl group Kara will release a new digital single "Mysterious" on March 9.

A teaser video and photo were uploaded at noon on Tuesday through the singer's official social media, showing Nicole standing against a black background and wearing a black suit.

"Mysterious" will be the singer's first new single since "You.F.O" was released last July.

Nicole debuted in 2007 as a part of girl group Kara, which is best known for hits “Pretty Girl” (2008), “Honey” (2008), “Mr.” (2009), “Step” (2011) and “Pandora” (2012).

Last November, the band got together for its 15th anniversary album, "Move Again." It was also Kara's first new album since its seventh EP “In Love,” released in May 2015.
