It seems as if you ask her out too early, it will be too direct/creepy, and she will reject you. This is because you don't know her yet. If you wait until after a few times you have interacted with her, you will get to know her and will be able to "game" her, but by that point it is too late because you would already be in the friendzone. It is damned if you do, damned if you don't.
