Denki was always used as a charger outlet for class 1-a. You never did that to him because you knew it bothered him. One day, he just snapped at class 1-a, he was sick of being an outlet and he stomped out of the room in anger. You went after him to see if he was ok. You found him sitting at a table alone. You walked to him and sat next to him

He didn’t say anything to you, so it looked like you needed to get his attention
