She will not understand that that's "wrong". For at least the first six months, if she seems to be trying to initiate sex, very gently stop her and ask her if there's something she wants. If she can't answer that question, ask her if there's something wrong. Repeatedly drill into her head that sex is something people do because they love each other and want to make each other feel good. Give her other ways to make you "feel good" that she can use to demonstrate that feeling, like making you a cup of tea, or playing music she thinks you'll like, and so on.
You will want to show her the whole world immediately, now that she's a free creature, but it'll be overwhelming and shocking for her. Gradually introduce her to pleasant things in civilization once a week or so, like going to the bookstore together, or going out for ice cream, or visiting a zoo. For the first three weeks or so, just take her grocery shopping with you.
Your water bill, electricity bill, and the money you spend on food will go up a little. It's unfortunate that you're a broke ass student. You don't have the financial resources to actually whisk her away to paradise, so you're going to have to be prepared to make do. Get her a cheap burner phone she can use. If you're in student housing, you can get away with a lot by bullying your way through, possibly having her sign up for a simple class.
Student loans are an ass rape without the courtesy of a handjob, but as long as you can keep your scholarship, this will make things easier for you both. You don't need to provide her with the Ritz. Sparkling apple juice, fairy lights, instant noodles, and a sane and clean environment where no one can hurt her will be paradise enough. Don't panic when you talk to her about money, but be sensible and realistic about what you can accomplish and invite her to help you think of ways to be practical.
Tell your parents and grandparents you've met the girl of your dreams and shamelessly extort money from them. Tell your female relatives thar if they disrespect her in any way they'll be dead to you, and only after that ask them for advice or to offer her friendship and warmth. Tell the dean of students that you failed your classes last semester because your fianceé's father was trying to kill her, and insist on having the Fs withdrawn from your record. Bully them.
Don't actually start talking to her seriously about marriage until you've made it a year out, do something nice for the three and sixth month anniversary of her rescue, and good fucking luck.
Let her read whatever sort of fantasy and science fiction she wants, as long as it isn't degenerate.
And make up your mind, right now, whether you're going to find your balls and ride this out with her for the long haul or whether you're just another romantic, spineless child kidding himself. She needs you to be a man amongst men, and for you to have the strength to hold her up when she collapses into chaos. Start with the Greeks.
