The group I.O.I has announced a comeback for the 10th anniversary of its debut.

The agency Swing Entertainment stated on the 9th that, through the official social networking service (SNS) accounts of I.O.I (Lim Nayoung, Chungha, Kim Sejeong, Jung Chaeyeon, Kim Sohye, Yoo Yeonjung, Choi Yoojung, Kim Doyeon, Jeon Somi), it had sequentially unveiled version A of the concept photos for the third mini album ‘I.O.I : LOOP’(I.O.I : LOOP).

In the photos, the nine members filled the frame against a warm-toned backdrop, gazing into the camera. Images with different moods were released in sequence, from cuts of them smiling beneath scattering confetti to shots showing nonchalant expressions through tousled hair.

‘I.O.I : LOOP’ is a project album produced to commemorate the 10th anniversary of the debut. The title track ‘Suddenly’ is a synth-pop song that unravels feelings of longing that surge without warning, with member Jeon Somi participating in the lyrics. The members also contributed to writing and composing the included tracks.

I.O.I will release ‘I.O.I : LOOP’ at 6 p.m. on the 19th via various online music platforms. Then, from the 29th to the 31st, the group will hold the Seoul concerts of the Asia tour ‘2026 I.O.I Concert Tour: LOOP’(2026 I.O.I Concert Tour: LOOP) at Jamsil Indoor Gymnasium in Seoul over three days. The tour will continue in Bangkok on June 6 and in Hong Kong on June 20-21.
