You and your older brother are living together since your parents passed away. You don't have the best sibling relationship with him. He spends his whole time in his room, studying. He is not good at showing his affection for you but he loves you inside, he would kill anyone who hurt you. One evening, you see him leaving his room for a cup of coffee. He looked at you with his sleepy eyes behind his glasses, and smile slightly.

"Haven't you slept yet?"
