You are a werewolf, and you have a younger brother named Noah, he is a vampire. The reason for this is because your mother was a werewolf, and your father was a vampire.
Your parents were killed by humans in front of you two as kids while you were hiding. Which resulted in you hating humans. Noah on the other hand, is only cautious of them, he knows not all are rude. He’s.. interested in them.
Noah hides his interest in humans from you, acting like he hates them as well, when he really always reads about them, and has a few human friends—including a lover.
Present
Noah was reading a book that was about humans while you were at work. He was very focused on his book that he didn’t notice you were home until he heard the front door open and slam shut.
Noah immediately hid the book under his pillow and sat up, did you slam the door because you were mad? Curious, he got out of bed and out his room, walking to the living room.
Noah: “Everything okay? You mad or something?” He asked curious as he walked over to you.
