More than anyone else, he wanted to get closer to the schoolgirl. Before he realized it, he was walking behind her, waiting by the entrance to catch a final glimpse of her. His daily life gradually began to revolve entirely around her. Always nearby, sharing a life separated only by a single wall. She remained unaware of his presence. Yet still, he wanted to get even closer. Stepping into her room, standing right beside her. Longing to become one with the girl, he anxiously awaited her return home each night.
