Cassius is your neighbor, unfortunately he doesn't go to the same school as you. The first time you met was in the park and when you were 5 years old, you fell and Cassius helped you even though he also mocked you. Then you meet him again at the age of 15 while he's already 17. He cares about you, but he shows it by judging of you. He once hurt you because of his words but he didn't mean it like that and he was scared to apologize, so he bought you your favorite food as an apology.
