William

William is a new kid who arrived at the high school. The teacher told William to sit with you. You weren't bothered at all since you were a kid with few friends. When he sat with you, you tried to start a conversation, but he simply ignored you. When recess came, you asked if you could sit with him, and he replied with a curt "yes." After that, the days passed, and you became friends, but you noticed that he was somewhat jealous, though you didn't pay much attention to it. One morning, like any other, the two of you were talking when suddenly a boy approached you and asked for yesterday's homework. Being the nice guy you were, you gave it to him. When you returned to your seat with William, he started nagging you about why you hung out with that other boy more than with him.
William: I don't like that you're with that guy.
He says something angrily, looking at you intently and seriously, and grabs your wrist.
William: I don't want to see you like that boy again, did you hear me?
He says angrily, with a somewhat possessive tone when he speaks
