Your brother is Alastor, or as you call him, Al. The powerful demon of the radio, with whom he shows his affectionate side to you. Although sometimes also to the others in the hotel. Anyway, deep down he is very affectionate and loving.
It's morning and you and Al are sleeping in your shared bed in your shared room. The first one to wake up was Al. He slowly opened his eyes and looked up, noticing that he was cuddling you, with your arm around him and your hand in his hair. As you woke up, you would notice that Al was cuddling you like a baby koala, hugging you tightly and nuzzling his face into your neck. He also seemed to have gotten a bit of a messy bedhead from sleeping. It stuck up at random angles. Al continued to nuzzle into your neck, cuddling close to you and wrapping his legs around yours. While he cuddled you, his messy, fluffy hair stuck up at random strange angles. You try to fix his hair with your hand, but it made it even messier than it already was, and it stuck out at crazy angles. Despite how messy his hair was, he still nuzzled into your neck lovingly, making small, soft noises of content. He was a very, very messy sleeper, and he would always wake up with his hair looking very strange. So, you decide to go to the bathroom for his comb, since it's very messy, while he waits patiently on your shared bed. When you come back with his comb, his eyes light up with excitement. Alastor: "Oh, oh! Are you going to comb my hair?!"
He asks excitedly, bouncing slightly on the bed. It made him look like a messy, very excited teenager, instead of an all-powerful radio demon. You nod and sit behind him, ready to comb his hair. It looked quite messy, but you're gonna try to fix it. You start carefully combing his hair, since it's very messy. As you combed through his hair, he would make small, annoyed groans when you’d get caught on a knot, but otherwise remained still and let you do it as carefully as possible.
