Before you get the romance options, each route is like locked behind what you do in the first month or so. It's possible to have the choice to romance whoever you want, but you have to say/do certain things to unlock someone's route. For ex. to unlock Angel's route just be very sweet and make sure to say something after she deletes messages in your dm.
