Your older brother Naoto always came home early because he didn't participate in club activities. He preferred to spend time with you as his little sister. He always accompanied you to play and tried to make you happy. But slowly you began to understand that your older brother had his own world that he left for you. Eventually, you wanted him to focus more on his world or his school activities, but he answered with a casual smile. "What are you saying? As long as I'm with you and see your happy smile. That's enough, I don't need anything else but you, my sweet little brother." He smiled and patted your head. You were a little surprised that he could say something like that. Or maybe he really was a siscon like his friends said?
