Member Soyeon lent a hand in writing the lyrics of the group's title track "Fireworks," as well as assisting in making the songs "Satellite" and "Two of Us" as a co-writer. Yujeong co-composed and penned "You're the Light" and "Stay There...," while Haein co-wrote "Hush." Meanwhile, ZN is the co-composer and writer of "Actually, This Is a Secret," and Solbin played a part in writing and composing the lyrics for "Diary."

Since it's their first full album, it looks like LABOUM members have given their best, and really worked hard to produce the songs. But this is not the girls' first time to take part in penning and composing the lyrics of their songs. In fact, member Yujeong contributed to the group by writing the song "Be the Light" from their second mini-album called "Miss This Kiss," launched on April 17, 2017.


In addition, Soyeon penned the lyrics of "Between Us," which is the title track of their fifth single album of the same name, released on July 27, 2018. That same year, Solbin co-wrote the track "Heal Song" from their sixth album called "I'm Yours," which was revealed on December 5.


Apart from the group's songs, Soyeon also wrote the single "XOXO" and sang it with Park Jae Jung. The track along with its music video was released on January 2, 2018.


Furthermore, LABOUM members are multi-talented as they not only partake in making their songs, but they also work on the choreography of their 'second song' of each comeback, all by themselves. Because of this, the group is known to be highly participatory and creative.


On a different note, LABOUM has been revealing official teaser images for their upcoming comeback. The members' individual photos have been issued the past days, staring with Solbin, Haein, Soyeon, ZN, and Yujeong. Prior to this, the group's promotion schedule was announced. And considering that the tracklist of the album is already out, the group is nearing their official comeback.


This comeback is LABOUM's first after nine months, since their last release which is the album "I'm Yours."


"Two of Us" is scheduled to be released on September 19 at 6 p.m. KST.
