"The Shadows in His Mind"

As Kageyama continued to write down the messages, Oikawa's concern grew. The messages were not only threatening, but they also seemed to be hinting at a deeper understanding of Kageyama's inner thoughts and feelings. It was as if the mysterious figure had access to Kageyama's mind, and was using that information to torment him. Oikawa's eyes scanned the pages of the notebook, his mind racing with questions. How was this possible? Was Kageyama's mind somehow being manipulated? He looked up at Kageyama, who was still scribbling down messages, his eyes wide with fear. "Kageyama, stop," Oikawa said, his voice firm but gentle. "We need to talk about this." Kageyama looked up, his eyes red-rimmed from lack of sleep. "What is it, Oikawa?" he asked, his voice barely above a whisper. Oikawa took a deep breath. "I think we need to see someone. A professional. Someone who can help us understand what's going on." Kageyama's face went pale. "You mean a psychiatrist?" he asked, his voice laced with fear. Oikawa nodded. "Yes, that's exactly what I mean. We need to get to the bottom of this. We can't just sit back and watch you suffer." Kageyama looked away, his eyes welling up with tears. Oikawa could see the fear and uncertainty in his eyes, and his heart went out to him. He knew that this was not going to be easy, but he was determined to help Kageyama. The next day, Oikawa made an appointment with a psychiatrist, and they set off for the session. As they sat in the waiting room, Kageyama's anxiety was palpable. He fidgeted with his hands, his eyes darting back and forth between the doors. When the psychiatrist called them in, Oikawa took a deep breath and stood up, leading Kageyama into the session. The psychiatrist, a kind-faced woman with a warm smile, greeted them and asked them to sit down. "So, tell me what's been going on," she said, her eyes locked on Kageyama. Kageyama hesitated, but Oikawa encouraged him to start. As Kageyama began to explain the situation, the psychiatrist listened intently, her expression growing more and more concerned. When Kageyama finished, she leaned back in her chair and steepled her fingers together. "I think I see," she said. "It sounds like Kageyama is experiencing a form of psychological manipulation. The messages, the voice in his head... it's all very real to him." Oikawa's eyes locked on the psychiatrist. "But how is this possible?" he asked. "Is someone actually controlling his mind?" The psychiatrist shook her head. "I don't think so. At least, not in the classical sense. But I do think that Kageyama is experiencing a form of psychological trauma. One that is manifesting in a very unusual way." Kageyama's eyes widened in fear. "What does that mean?" he asked, his voice barely above a whisper. The psychiatrist's expression was kind. "It means that we need to work together to uncover the root cause of this trauma. And once we do, we can start to work on healing." As the session came to a close, Oikawa felt a glimmer of hope. Maybe, just maybe, they could get to the bottom of this after all. But as they left the psychiatrist's office, Kageyama's phone suddenly buzzed in his pocket. Oikawa's heart sank. "Kageyama, no," he whispered, but it was too late. Kageyama's eyes locked on the screen, and his face went white. "It just sent me a message," he whispered, his voice trembling with fear. Oikawa's eyes scanned the screen, but there was nothing there. Just a blank screen, with a single word: "Hello".
