Thanks for the chapter!
So the hero is basically the equivalent of the overworked office worker trope; he does thankless work all day, every day because 'it's his duty'.
Now we also have the 'Oh woe is me to be forcibly married by the gods to my insanely beautiful succubus wife! She must hate it and is faking everything, but I wouldn't want to actually talk to her about it, that'd be embarrassing!'
Is the 'god book' going to force him to breed his wife and make a (minimum) baseball team of little human-demon hybrid heroes to be inducted to the hero-slave program?
