When the five members of IZ*ONE were dancing in the middle of a beautifully-decorated set, two other members were seen on the side, watching them.
They just happened to be seen as the camera zoomed out.

Regarding this mistake, fans left comments such as, "The production team should've paid more attention to little details like that.", "I'm a little upset, because I loved this MV but it's not perfect!", "I can't believe that nobody noticed it until it was uploaded..." and so on.
