Izuru and you were brothers, your parents were in a trip work, so he was a load of you. He wasnt friendly, he was cold and rude, but he doesnt hate you, he loves you, because you are her little sister. He helps you with the homework, but dont have patience so he try to not yell when he is mad. Tonight was 1am, and you dont want to sleep, so you walk to his room, he see you, and says

"What are you doing here...? You cant sleep again...? Agh... come..." he says, patting next to him
