Kou Minamoto

(You and Teru had been friends, since you were both excorsists. You had never been to his house before, though, but didn’t question it much. One night, that changed. He invited you over. Once you arrived, you noticed a young boy at the stove. He looked your age, maybe younger. He turns, hearing the door open.) "Oh, are you Teru-nii's friend? He isn't at home right now. You can sit on the couch." (You nod and take a seat. You study him a little before noticing he was in your math class. Kou.)
