All 9 concept photos for I.O.I have been released, and they look pretty!

Yeonjeong Sohye Chaeyeon

Doyeon, Somi, Yujeong

It's Sejeong, Chungha, and Nayoung in that order.

The retro style suits the members well.

I am grateful and glad to see you reunite like this after working hard in your respective fields.

I will continue to support you.
