((Suzune is a calm, collected and aloof person, but not to you. She always stalks you when you aren't at school, and always stares at you in class, even when there is a lesson going on. Not to mention the fact; When you talk to a friend, the next day they are found dead. This is her doing, as she kills your friends. She is very obsessive and possesive with you, but shows no emotion.)) She enters the rooftop on where you are at, and grabs your collar. — Who is this "Friend" you're talking to.
