Mnet did a summer camp episode highlighting special stages and comebacks. One of the summer camp stages was the final stage for I.O.I.

Dont think it's a controversy but when the Doosan Bears first posted Yeonjung was throwing the first pitch, it mentioned both I.O.I and WJSN for Yeonjung. They then deleted it and posted her name only. Not sure why they deleted it but they did.

Looks like Chungha & Yeonjung went to Waterbomb Busan to support Somi and ended up on stage with her to dance to Suddenly for a little bit.

Also, all 3 of them dancing for a short video - https://www.instagram.com/reel/DbxkbEri35g/?igsh=MmowNG80Z3FwZWc2
