Good art, good girl designs, barely passable story (so far).
As of chapter 40, the synopsis of the story is misleading as none of the women persecuted Evan. Turned a blind eye at most, sure but none of them physically abused Evan like the ugly bastard master did to him or played a role in helping Evan become a slave. Also, I'm not sure what revenge Evan is looking to extract after he took out the ugly bastard master. His revenge feels aimless because he doesn't have a grand goal in mind.
Overall, if you turn your brain off and enjoy the sex scenes, then this series is not bad.
