Just something that I realised when I was repeatedly watching 'Kiss as long as eternity' video.
Are the square, numbered items mailboxes!? I'm not really sure about it.
Anyway, the numbers are in sequence except this one box of number 247, which is below 116.
Another one of sequence error,
This time it's box 246 which is below 214.
My guess is that mailbox no.215 and 117 were kind of dirty/damaged/scratched/whatever, thus, they were replaced by other mailboxes which supposedly be 'cleaner' for the sake of video-recording.
Ahahahahha, this is what happens when I really have nothing to do.
