I.O.I is making a comeback to the music industry to celebrate their 10th debut anniversary. Swing Entertainment announced on the 23rd, "I.O.I (Lim Nayoung, Chungha, Kim Sejeong, Jung Chaeyeon, Kim Sohye, Yoo Yeonjeong, Choi Yoojung, Kim Doyeon, Jeon Somi) has confirmed their comeback in May," adding, "They are currently preparing a new album."

This comeback marks a reunion after about nine years since 2017 and holds great significance in commemorating I.O.I's 10th debut anniversary. The members have consistently expressed their intention to reunite through various interviews and official appearances, and after long discussions, they have come together again.

However, Kang Mina and Zhou Jieqiong will not participate in this activity due to prior schedules. I.O.I will return as a nine-member group, and since the members have built active careers as solo artists, actors, and entertainers in their respective fields, expectations are high for new music and upgraded performances.

I.O.I is a project group formed through a national vote on Mnet's Produce 101 in 2016. They officially debuted in May of the same year with "Dream Girls" and quickly established themselves as a leading girl group in the music industry by releasing numerous hit songs such as "Whatta Man," "Very Very Very," and "Sonagi."

They dominated music show first places and top positions on major music charts, proving their unique presence by winning rookie awards at major award ceremonies such as the Mnet Asian Music Awards, Golden Disc Awards, and Seoul Music Awards. In addition to their music activities, they solidified their position as the "national girl group" by actively participating in various entertainment programs.

I.O.I officially concluded their activities with a concert in January 2017. Along with the release of this album, they plan to hold a concert in Seoul followed by an Asia tour. They are planning to meet global fans directly and promise performances that will quench the thirst of fans who have waited for nine years.

Detailed schedules and album information regarding I.O.I's 10th anniversary comeback will be released sequentially in the future. The members' anticipation for reuniting with fans is growing, and attention is focused on what achievements this activity will bring.
