The girls of I.O.I have made their comeback stage on 'M Countdown' with 'Very, Very, Very,' on October 20.

The group debuted in May 4, 2016 with their first mini-album, 'Chrysalis,' and title track, 'Dream Girls.' Since their debut, the girls have had much success with their first mini album and subunit collaboration release. It's great to see the girls on stage together again!
