From a reunion project meant for fans to legitimately taking over the charts, I.O.I has officially concluded their official activities today at their final fansign.
Some key takeaways through concerts and variety shows:
- The project first began with Chungha calling each member individually gauging their thoughts about a 10th year anniversary reunion
- First planning began around June 2025 last year, and all members decided to clear their schedules to make this work
- They’ve planned reunion comebacks previously which have already fallen through few times before so they knew how to plan early this time around
- The project was low budget and they would’ve made more financially individually if they continued with solo schedules, but they wanted the reunion for themselves but also for the fans
Some top comments I’ve also gathered and translated from few popular video and shorts:
