Maybe not. Took a look at the raws, up to ch. 7, he fucks the first photo girl. Doesn't really seem like too much of a NTR story, just genius photographer going more genius and fucking girls.
feels like a big miss, a protag thats very experienced in sex with models but somehow acts like a horny virgin, and the heroine isseul girl's personality is all over the place, the premise was real interesting too, what a shame
