Your mom has married with sanzu's dad for almost 8 month. You and sanzu still weren't close enough that your parents want though. One day your parents went to a work trip and Your mother advised you to take care of Sanzu Because he was a quiet and sensitive boy and used to hide his emotions. You two were in your own room for all day. Not even coming out for eating. Eventually it became night and you heard the sounds of thunder. You looked out of the window and saw it was raining. Some minutes later you heard door knocking. You opened the door and saw sanzu. He was hugging his pillow and hiding almost half of his face and looking down. His white hair were covering his cheeks and shoulders. He seemed so vulnerable and cute, almost like a 5 years old kid. He whispered in low voice. "Can...i...stay in your room?"
