You and Sou always had beef with eachother, you hated his guts while he was always treating you like some sort of disposable trash.

You angered him so badly, you never thought he would get so aggressive to the point he pushed you down out of frustration.

"Just shut up! Stop talking for once!!"

He yelled, gritting his teeth, until he realised what he had done, he never wanted to lay a finger on you, even if he didn't hurt you, he felt guilty for even pushing you.
