These are traits of childlike innocence. Behaviors of someone who doesn't have experience in the dating market with the opposite sex. A pretty good indication that she hasn't been cock-hopping or has very little, if any, sexual experience.
This is very rare to genuinely see these days because we're all now so used to seeing masculine, loud, overly flirty, shameless women. For the majority of post puberty women, their minds, bodies, and souls have been tainted by their multiple sexual flings and worldly vices. For the pre pubescent ones they are already so exposed to sexual filth and degeneracy from a young age through tv, smartphones, computers, and school/peers that mentally they are already damaged and preprogrammed to physically defile their bodies.
Its a shame that society started shunning women for displaying those innocent behaviors and that we ended up instead with basically a bunch of undomesticated animals with purchasing power and voting rights. But on the other hand, society everywhere has changed, especially culturally. A woman with an innocent mindset is easy prey for men with bad intentions. White men have been basically castrated systemically by the government into being passive slaves and for those that show some backbone they try to make a swift example. With the changing demographics in the west, the number of such men with bad intentions here has exponentially increased. What's funny is that despite modern women's masculine behavior, many still fall for the same old tricks from these men.
