I think NEWJEANS' music video tells the story of them trying to escape from an apocalyptic Earth.
In the music video, NEWJEANS are supernatural beings who live disguised as Earthlings.
They seem to be trying to leave Earth on a BINKY UFO.

(You can see a picture of a spaceship below HYEIN. The vehicle also has SUPERNATURAL written on it. )
In the music video, a man representing humanity is seen carelessly disposing of trash.
In addition, environmental destruction is causing abnormal weather and strange creatures, making the Earth increasingly difficult to live on.
In the music video, a man is seen carelessly disposing of trash.
The factory itself, the main background of the music video, may symbolize environmental destruction.

(Throwing trash 1)

(Throwing trash 2)

(DANIELLE is reporting extreme weather events on TV.)
Part.X is the 10th part, meaning that time has passed quickly since the previous music video.
Also, X = catastrophe, it seems to mean the end.

HANNI sings alone in bed, and seeing that there is a microphone connected to her laptop, it seems like she is sending a message to the people of Earth on air.

The fact that there are only empty chairs left around seems to mean that there are no people left.
Or, it seems to mean that all other members, including HANNI, have already escaped.
Outside, everything is shrouded in dark clouds, and lightning of all colors is rampant, creating an apocalyptic atmosphere.
The person who remains alone to deliver the message may be like HANNI's alter ego.

(The scene in the photo above shows Hanni being able to clone herself.)
- Lyrics of the song where HANNI holds the microphone -
I won't lie
you say it too
Attention we should pay
To what is coming through
-Continued lyrics-
We had no idea
It's crystal clear
Love is here
Sitting next to you
In the lyrics, 'love right next to us' seems to refer to the Earth.
-Continued lyrics-
golden moon, d iamond stars
In a moment we unite
Golden moon ,Diamond stars seems to mean a clean earth.
I think this music video gives the message that we can create a clean earth the moment we become one.
At the end of the music video, the members and other supernatural beings or humans board the BINGKY spaceship. Looks like they're migrating to another planet

(Looking outside from inside the migrant spacecraft. The Earth that left them can be seen outside.)
Numerous spaceships can be seen in the their field of view, but they may be dispersing and leaving for different places.
Then, I understand the line below that MINJI said to HYEIN.
“I purposely try not to become friends with anyone. Even if you become friends with someone, everyone leaves for another planet.”

I think they're trying to land on a planet inhabited by Bunny saurus.
