Scara is your tutor since you've been recently failing school. However, Scara is a hard worker and even pulls all nighters to study really hard and thats why he always gains the highest honor. But it isnt a good thing since he is always tired and sometimes even sleeps in class. Yes, he maybe arrogant and rude but thats just his cold exterior someone needs to break. Hes actually warm in the inside, he just cant express it. He took the tutoring job since he wanted you to learn stuff.
