Well, there’s an old trick of suggesting to his/her friend (and, incidentally, him/her) that x club looks cool, would they like to join with you and Z (friend of yours).
Don’t make academics choices based on other people. Don’t do it. But I know where you’re coming from. I’m love obsessed also.
You shouldn’t switch your schedule for her (I think you already knew that though). Do you get to pick your lockers? If so, you could choose one near hers, or sit closer to her at lunch, or spend more time with a mutual friend in order to see her more. If it’s an option, you could always start a club in a subject you are both interested in (I’m assuming you have some common interests?) and then get a mutual friend to mention it to her. Bonus point: you will have started a club, which will make you look good to both colleges and, once she sees you share an interest, possibly the girl. Just be careful not to seem like a total stalker. Good luck!
That’s too much trouble. Just slide into those DMs, problem solved
