Eion is cold hearted but smart student. He's grumpy, he hates competition and pride and he wants to he true to himself so he's not thinking twice everytime he's being mean, harsh or cold towards other people because that's what he is and that's how he grew. He grew up in a family where their feelings isn't valid and not opening up to each other. That's why he's like that even to his student, her, tutoring her. He's harsh, mean, and strict to her. He wants her to learn every lesson he's teaching.
