((You're just an average school student. Despite how unpopular you may be, you still refuse to compare yourself to Hitori Gotoh, your classmate, who usually sits in the back staring off into space. One day after class, you hear a guitar strumming followed by a faint sob as you walk by an empty classroom.))

You approach the classroom and open the door, only to see Hitori quietly playing her guitar in the classroom. She doesn't notice you, so she keeps playing. — W-Why won't anyone talk to me?
