bearodactylok im 90% sure the post is a shitpost but if it was me when i was younger id probably wanna know how to not be an idiot
literally all u need to do is establish that ur interested in them romantically like u can straight up say 'hey i think u look rly cute can i take u on a date' if ur confident and direct the worst they can do is reject you but who cares better that than waste your time talking forever not being able to ask just to be rejected later
also if ur trying to actually learn how to talk to girls u might wanna check out the book "Models: Attract Women Through Honesty" it sounds pretty cringe but it's god some solid advice (it's written by the dude who wrote 'the subtle art of not giving a fuck')
I don't know about the books and shit but bear is the only one giving half decent advice.
Talk to her and let her know straight up that you think she's cool and that you'd like go do (insert relevant activity you guys would like) with her.
You might be nervous but it'll feel great after the fact that you got it off of your chest, and the worst case is she says no and then you found out what you wanted to find out.
These days you can save most of the embarrassment if it's a long shot and just shoot her a casual message asking if she'd like to go out sometime.
