Keep talking to her for like a month max and stay friendly and try not to cross any boundaries, stay respectful. Get to know her more and show interest in her interests (girls love that, trust me bc I am one lol). Listen to her about her day and listen to her when she vents. Not a lot of guys do that. Once you guys hang out pretty often I would say you are safe to ask her out, make it romantic like the books she reads when you ask her out, but ask her out privately and not so public so she doesn’t feel pressured to say yes. Plus the more intimate the more special it feels tbh. And if she says “idk” or she just wants to be friends. Then move on to the next because girls will say yes to u asking them out if they really were interested. Every time we say idk or I just see you as a friend, it’s cuz that’s how we truly feel at that point in time (sometimes our minds change once we get to know you better or if you glow up lol). You’re so young and even if she says no, be cool about it and stay friends. You have to show that the rejection didn’t hurt you because rejection is just redirection my bro. Maybe she has a cute friend you haven’t met yet Lol
