I'm sorry but his grandma needs to go, he has to put up all this just for his grandma and go through it even if it's to much for him. If his grandma goes then all his problems will be solved
@Shiko yun I must say this is true I already thought from the beginning that it doesent make any sense that he tries to cure his grandma bc she's already so old even if she would get out of the hospital she would die shortly after
