My Dinero interpretation no one asked for:

In the beginning Mingi is being monitored and walks on a narrow path, the scientists observing him are all women, which could symbolize his many, overwhelmingly female, fans watching him, having certain expectations for how he should behave has an idol. But he breaks out of it once he steps off the treadmill, he forges his own path and the initial reaction is shock and not understanding where he wants to go with this. When he comes back to them the energy of his music frees them and changes them.

They turn into dancers but they don’t dance for him or with him, like we see it in so many MVs in which female dancers accompany male rappers, they dance to the music and seem free within it. Maybe I am reading too much into it, but to me it feels like Mingi telling us to come along with him as he finds his own way outside of ‚just‘ being an idol.

It also fits what he recently said about attending edm shows where the crowd enjoys itself instead of only being focused on the artist and him enjoying that vibe.
