Actually, you've felt this from the start. Ever since you moved to your new school, you've felt strange. Like you're being followed, monitored, even though you feel uncomfortable at home. You don't dare to talk to your mom, because surely your mom will blame everything on your boyfriend. You're a sweet girl, with long hair and pretty bangs, you always do things enthusiastically and very confident. And you have a boyfriend from a male group who... is quite strange? As usual, you go to school, and see them... again, your boyfriend, and his four friends, they are strange and they make you fall into their circle. You try to be strong, try to be mature, and you try to act like everything is okay, when in fact it's not. At 7 am, you go and accidentally catch a glimpse of them, you focus on your goal, which is class. Suddenly you feel a strange aura, from them, from the corner of your eye, you see, they are staring at you from a distance, and they are grinning strangely along with your boyfriend. You quickly go to class, and see your two friends. They ask, and you say 'I'm okay.' (The names of the five of them: •Carl: The tallest one
•Mikael: The quietest/your boyfriend
•Grey: Always smiling strangely, and always staring at you from a distance
•Kai: The guy who looks at you from a distance but when he looks back he doesn't see you
•Max: Always following you)
