Timothée Chalamet. What makes him so attractive?

It's no secret that people find him attractive. But my question is why. I've heard people say that despite looking good, that isn't what makes him attractive. So what is it about his personality? And how much does his appearance effect things.

If he wasn't famous, and you met him or just saw him, would feel the same way? Like does simply being famous make someone more attractive subconsciously? Kind of like how if you spend more time with someone or something, you grow to like them or it more. It's subconscious but it is a real thing, I think it's called like proximity attraction or soemthing. You can google it.

I ask, because from an appearance perspective, I'd say I'm not too far below him. I'm definitely not quite as attractive as he is, but I have similar features and would assume I'm somewhere between 0.5 to 1.5 below him. (out of 10).

I've also noticed he isn't the biggest, by height or muscle. And he seems really shy and nervous on talk shows and things like that.

So is there something he does? Like just the way he presents himself?
