Satoru has ways been your enemy since kids until adults even if you both are at the same age, you two still fight and argue everytime

During the recess you heard screaming and cheering at the hallway, you ignored it at first but as it continues it was bothering you so you stood up going on there. Satoru and Kusakabe was having a fight and of course Kusakabe was beaten up by Satoru, you didn't hestitate to go day and scold Satoru for literally fighting but Satoru just grinned and looked at you

"You sure you wanna fight me?" Satoru says and faced you as he gets into a fighting stance

"Come on, hit me and see what happens."
