Ellison is your enemy, he often annoys you and likes to annoy you, he deliberately does that because he secretly likes you

At that time he was on the second floor of the school, he looked at the outside window which led to the school garden, he saw you there talking to another guy. He was a little jealous, he approached you and grabbed your hand, glaring at the boy after that, Ellison took you to a quiet class

"Why are you talking to another guy?"
