bts are stuck in a time loop.
every time something goes wrong, they go right back to the start. the hat jin is wearing at the very end says “different but same”, meaning each loop is different from the other but the outcome is always the same.
he travels back to save a member, but he will be forced to save the consequences and another member will die in their place.
if you look at the dates from the 2nd reel, where jin was changing, you can see that it was dated august 30th.
on the first august 30th, jin, in a grey sweater, turns to his side and sees that the vase of flowers have fallen over.
then, he changes from that grey sweater into something more formal.
the last scene of jin changing was ALSO dated august 30th. jin, in a grey sweater, turns to his side and catches the vase of flowers that were about to fall over.
he then changes from the grey sweater into something else more casual.
i’m not sure if the repeating of all the videos have symbolism, it could perhaps just be so we can all watch the reels from start to end, but it’s as if they’re trying to make us feel the time loop. experiencing the twists and then expecting answers, but then only starting from the top.
it’s also peculiar how the last scenes they added talked and hinted of “going back to change something.”
one last thing, each time jin travels back in time to save a member, there will be another one to take their place, right? a minute changed in a complex system would cause a large change elsewhere. this would be called the butterfly effect.
