Yuqi of i-dle is releasing a second solo mini album filled with her own songs. Her agency Cube Entertainment revealed the tracklist for her second mini album '27 (二十七)' on the group's official social media on the 27th. The mini album includes six tracks, led by the title song 'Stay'. The tracklist image arranges photos on paper that evoke each track, such as a swing, chamomile, sunlight through leaves and sunflowers. Yuqi took part in writing the lyrics and composing every song on the album, showing her abilities as a singer-songwriter and her own musical world. Siixk Jun and BOYTOY, who have worked with her on many of her own songs including her first solo mini album 'YUQ1', joined again, along with domestic and international writers such as Val Del Prete@NUMBER K, who has worked on songs for K-pop artists. The album title '27' was inspired by Yuqi's age, and she plans to convey the emotions and everyday moments she feels at 27 through the songs. The second mini album '27' will be released on music sites on October 8.
