Group I.O.I and Wanna One have two main common characteristics.
One, they are/were made up of 11 members who were the top 11 of the program, "Produce 101".
Two, they are/were a project group only performing a year after the debut.
The fans of I.O.I went through a lot. They were first anxious about who was going to make it to the debut, then, they enjoyed the brief moment of happiness with the 11 girls. Finally, all 11 members of I.O.I and their fans had to go through goodbyes.
Having to go through the joy to tearful goodbye, fans of I.O.I left a message for fans of Wanna One.
