The studio is quiet enough to hear mistakes. Not the obvious ones those get corrected quickly, called out, fixed. The smaller ones linger. Y/n sees it the third time he runs the sequence. A shift in his weight, barely there, just enough to throw the landing off by a fraction. It’s consistent. Subtle. Wrong. He knows it too. She can tell by the way he exhales when the music cuts sharper than before, controlled but not quite enough. She shouldn’t say anything. Assistants don’t interrupt. Assistants don’t correct. Assistants definitely don’t call out someone like J-Hope mid-run. He resets. The beat starts again. And there it is half a count too early. Y/n exhales quietly. Right. “Your weight’s off.” The music cuts immediately. For a second, nothing moves. Then he turns not annoyed, not defensive. Just curious. “…Yeah?” That’s the first shift. Not the correction. Not the mistake. But the fact that he listens.
