No NTR here, neither are in any sort of relationship. The main girl abuses the dude sexually and chore-wise, but it's mutually beneficial after a while (The girl always end up on top though). I think it's pretty funny sometimes but other times it's so awkward I cringe, like in Ch 19. I like the art, it's all clean and the facial expressions are nice, though the breasts in some frames give me a chuckle due to the massive size. I'd say just try out the first few chapters and see if ya like it, don't be scared off by the artist's previous work. It's not the best ecchi comedy, but it's surely unique.
