It was Kim Se Jung who brought up the topic, saying, "In 5-10 years, I want to stand on stage with IOI again." 

The rest of the members cheered, and 'With You' member Kim Sook began planning out IOI's reunion! Kim Sook stated, "We [Kim Sook and Yoon Jung Soo] will MC for you guys  5-10 years from now. You guys promise to return as 11 members and perform 'Pick Me' and 'Dream Girls'." 

The girls then voted to regroup in 5 years rather than 10, concluding that on May 31, 2021, IOI would regroup. 

Will you be sad to see IOI disband eventually by the end of 2016?
