TXT - Eternally MV Explanation

Section 1

Section 1 is called The night of the end.

"On the night of the end, the world became fragmented or ruined. The boys' night was also dyed with darkness. The scheduled memory of the future was slowly eroding the boys. The boys wandered through the maze of nightmares and asked: 'Are there any other options for us?'"

That's how the MV starts before we witness 5 members standing in the middle of the chaos.
The pretty monstrous versions of each members were shown. In addition to that, Yeonjun had blood all over his face as we see when Soobin finds a book and goes towards him, also calling out to him as "Yeonjun-hyung". But once he sees Yeonjun's face, he freaks out and wakes up.
The members are all in the room, in which everyone was busy with something. Kai was dancing under Yeonjun's watch, while Taehyun was simply listening to music and Beomgyu was recording everything, and even Soobin, but. Soobin has a pretty worried expression on his face that NO ONE seems to notice. Beomgyu literally had camera on Soobin, but didn't bother asking if something is wrong. It may be, because Soobin is invisible.

On the official site, there are members' 'accounts', and each one of them has a numbered code in the description. Soobin's literally translates as "invisible".
In the photos, he might not be mentioned and in one of them, he is literally mentioned as 'invisible'.

It could be that Beomgyu simply didn't see him and was recording 'his own reflection' in the mirror.

Then, the clock goes one second backwards and some crazy stuff starts to happen. Well, the earthquake happens, but we can also see that something is written on the windows, and mirrors. Some of them are even written backwards.

From what I translated, that's what the inscriptions said:

"Find more in the sky."

"Will we eventually become like this?"

"What are we doing?"

"Don't go to 10,000 people." (This one was hard to understand; so sorry if it doesn't make sense) Edit: I tried again and it gave me "Don't go up the stairs." I think that one makes much more sence.

"I need to get out of the room."

"I can't breathe."

After that, Soobin runs to the door and then Section 2 starts.

But before moving on, I just want to point out some things.

The phrase "Will we eventually become like this?". I believe that this is literally what the boys are thinking. In the beginning they were shown as monstrous creatures, so it could be their worry. Remember that Yeonjun already had horns that he broke because was scared of becoming a monster in Nap of the Star.
"I need to get out of this room." This could also be one of the thoughts. Specifically Soobin's since he is the one to run to the door.

The phrase "I can't breathe." This phrase has reminded me of Taehyun's 'post' on the site, where he is mentioned as 'breathe'.

The phrases can also be the messages from the future to themselves.
