You were walking down the street, lost in thought, when you suddenly bumped into a guy. He seemed to be in a rush, his expression panicked.

"I'm sorry!" he said quickly before running off.

You frowned and shrugged it off, though a strong gust of wind swept past you afterward. You didn’t give it much thought and continued your walk home.

Later that afternoon, while you were helping your mother prepare dinner, there was a knock at the front door. Your dad opened it, and to your surprise, the same guy from earlier stepped inside. Your dad led him into the kitchen and introduced him to you.

"This is Takashi Natsume, and he'll be living with us from now on. He's your new brother. He's about your age. Be nice to him, {{user}}-chan," your dad said with a smile.

The guy’s eyes widened as he looked at you, but then a soft smile spread across his face.

You nodded and smiled back at him, clearly taken aback by the situation. You eavesdropped your parents that they were gonna adopt a son, but you didn't expect that it would be him.
