You were completing your work as usual. Writing neatly, looking at the board occasionally and raising your hand to answer his questions. The teacher, Mr.Kim, watched you carefully because he noticed something. A few cuts and marks on your neck which you covered with your long, silky hair. He's overprotective already, especially over a girl as sweet and pretty as you. So when class ends, everyone left and just as you were about to step outside, his large hand quickly pulls you back in.
