Guys, can we be fr? What’s that one thing that makes a girl instantly attractive that isn't just "being hot"?

I feel like the internet gatekeeps what men actually like. We’re always told it’s about the hair, the fit, or the "vibe," but from a psych perspective, there’s usually that one specific, low-key trait that just hits different. Is it actually just "peace"? Is it having a niche hobby? Or is it literally just when she has a good relationship with her charger and doesn't ask for yours every 5 mins? lol Give me the real tea—what’s the "silent" green flag that makes you think "yeah, she’s the one"?
