I like the concept of Demon/ human master/servant dynamics. The demon is a recluse, the servant is his only companion so he secretly cherishes him & they get intimate. Demon's feelings finally show when he hears the servant is on trouble & saves him.
All of that was a cool start! But then they started fucking it up by victim blaming & beating the servant, then fucking him. Like bro, the fuck? Darn so much potential. Imma have to make a doujin now
Everything was fine until he said "father". (⊙…⊙ )
