Okay but why did he have to go to the hospital? What was wrong with him?

stress?

I just gueesed cause maybe school and the fact that he has no one to take care of him and that hes worried for his mom , so it might not be stress maybe he just caught a cold who knows ╮(￣▽￣)╭

But what if it was for another reason. In another chapter it showed him in pain in the floor unable to call for help. What if it's something else
