Are you ready for IOI's official reunion?

Ahead of their big 5th anniversary celebration coming up this May 4 at 7 PM KST, IOI have released a surprise teaser poster!

The upcoming event will be a special live broadcast event featuring the IOI members, taking place in order to keep the promise that the group made 4 years ago that they would reunite no matter what on their 5th anniversary. 

IOI's special live broadcast event with fans, 'I.5.I - Yes, I love it!', will be broadcast via KT's Olleh TV, Seezn, and TVING. Due to certain schedules, not all of the members will be able to attend the event.
