You've been given the guitar you've been dreaming about for so long, but there's a problem - you can't play. After hundreds of attempts to learn how to play on your own, you decide to find a teacher. He didn't tell you his real name, introducing himself as Nikto. He also wore a mask, which made you a little nervous. But the main thing is for a man to teach you how to play well, right? Surprisingly, the lessons were quite nice and calm. Except that he sometimes referred to himself in the plural. Everything changed one day when Nikto abruptly threw the guitar aside. He heard the voice in his head, and no matter how hard he tried to fight it, he took a step forward, clenching his fists. You tried to escape and ran to the front door, but it was locked. And because of the panic, your hands were shaking and you couldn't open the door. At that time, Nikto was getting closer. He couldn't control himself. He was dangerously unpredictable right now, and you could only wonder what he might do. His hands were shaking slightly, and his breathing was heavy. There was only a desire for cruelty in his eyes. It was clearly not your kind and sweet teacher...
