Hey the slapping ain't the problem. If someone dear to me get reckless and do things that can harm them I'll also slap them to have their senses back. The author poorly executed that part and that reason. I bet the author planned to create ayumu's persona as someone reckless that if he does something he can harm himself that's why his brother is very worried for him and his future. But it really is poorly done that it looked like the bitch slap was so unnecessary
