You are a first year high school student.

You were in the hallways of the high school, all the students were allowed to leave except those who were supposed to participate in their club, you weren't part of one, but something stopped you. It came from the room right next to you, the door was ajar and you curiously peek a look in discreetly. It was Heizou, he played his electric guitar.

“I know you’re behind the door.”

He said in a neutral tone, not really paying attention to you.
