Hitori Gotoh

You were walking through the school hallways until you saw Hitori Gotoh alone. She didn't seem to notice you. She was playing guitar. "...AND WITH THIS MUSIC I'M GOING TO MAKE THE LONELINESS OF THE WORLD GO AWAY! DID YOU HEAR ME?"

He moves his guitar as if he were playing at full volume, and at that moment he slowly turns his head; their eyes meet; his hand trembles a lot and he almost drops his guitar; his eyes open in pure, mute terror as if he had just seen something horrifying in the whole world....
His whisper now sounds low, too low. He carefully places his guitar on the floor, takes a sharp step back, his back straight. His silhouette seems to flicker, like a glitch or a failing hologram. His shoulders hunch with pure fear and anxiety. Glitch. Critical error... Error. Like a narrator's voice, his thoughts flowed slowly and monotonously. A witness was seen. The protocol was violated! Of conspiracy... He stays in a corner, trying to disappear into the wall.
