Hold on, so I just remembered how a while back there was all that drama when there was a big off collab in Japan and they didn't wait for Pomu to arrive even though she would be there literally the next day, so she was the only one left out. Which led to a lot of speculation that it was because she was going to graduate. But people were insistent it was a nothingburger and eventually I forgot about it. But now that we know she actually is graduating, is it possible it was a somethingburger after all and Pomu was already planning to graduate even back then?
