She can go on dates with them, hang out with them after school, sometimes even visit their rooms. It's okay if she develops feelings straight away or if she wants to lead the guy on for a bit. It might even be okay for her to form a love triangle...? The endings will change based on the choices you make. Would you like to live out an exciting romance, with a demon to boot?
