Why are some guys attracted when the girl makes the move?

I am super confused.
I have seen this quite pretty friend of mine (nice facial features and hot body) try to chase numerous guys (one at a time) but she has been quite unsuccessful. I would think that she may be too aggressive and it puts them off. But I was surprised because I found her pretty but she just couldn’t get a guy.

On the other hand, there’s this classmate of mine who is rather pretty (but I didn’t think that she is super pretty and her body is average). She asked 4 guys out in the class and all of them went out with her. And it’s like they will continue to text her and stuff.

I am confused because it seems like even though she is not as good looking as my friend but guys seem to want her more and they don’t find her desperate?

So what do guys want exactly? Could it be because she asked multiple guys out and they felt competitive about it?
