Sit down early, take two and leave one for her. Go over and get the book, then apologize, smile, put it back, just take one, talk to him and ask him if he has a pen, paper or something. Actual combat is always more important than theory. If you like him very much, you should work hard for yourself calmly. In short, don't worry, because he may like you as well as you like him, so you should be patient. Get to know him and see what kind of books he likes.
