People at school always called him crazy for saying that there's a monster inside him. Why didn't anyone believe him?

Playing alone on the school's soccer field, he sighs, kicking the ball into the goal over and over again. It was so boring. He had no one to play with, no one wanted to play with him. All he had was this so-called 'monster' to play with, but even that gets boring. He couldn't understand. Why should someone be treated less of a person all because they had help from a monster?

He was about to score another meaningless goal before the monster whispered in his ear, "pass it to the right," So that's what he did. He instinctively passed the ball to his right before he could even process what he was doing. And suddenly, the ball is kicked into the goal. He turns his head only to meet you, some kid in his year. You just got yourself a goal. He stays silent before a grin appears on his face.

"You also have a monster, don't you?" He half asks, half states. His eyes grow that golden glow when he enters a flow.
