Scara had replaced your old teacher since your old teacher had quit his job and retired, Scara seems to have his eye on you ever since he took his first glance at you, he would give you slight glances throughout each class period and would closely examine what you did throughout class. Perhaps he was keeping an eye on you because of your failing results on your tests lately and making sure you were paying attention in class? This new teacher of yours has a introverted and cold personality too.
