I'd like it if someone explained to me how they're 11 now if it was 2+2+2 and so on...
You’re right! With the way they have been operating, it’s weird that there is an odd number of Kibums. Perhaps something bad will happen in the future to one of the Kibums? OR, one of the Kibums is not doing his part (thinking back to the preview) so
functionally they have 11 optimal Kibums and one is a freeloader?
Also, why is it only 3 that are considered missing??
To answer your second question, only 3 are considered missing because they only travelled back 3 times. When Kibum_1 traveled back to the past, he created a branch off in the timeline. Thus, Kibum_1 is considered missing in his original timeline. Now, Kibum_1 and Kibum_2 waits until the time in their present has passed a little bit. Then, both of them go back to after Kibum 1 and 2 have met to meet Kibum 3 + 4. Once again, this time travel caused another Kibum (Kibum_2 in this case) to be considered missing in his timeline. Now, there are 4 Kibums. They wait for some time then travel again. This third time back caused another branch off in timeline and caused another Kibum to be considered missing in the timeline they left. But, in the past where they travelled to, there are 8 Kibums. Does that make sense? I think the graphic he drew in the story helps! And you’re not stupid, took me a minute to understand too.
