Bro its obvious the author wants the brown hair girl and him to end up together but cmon at least think of a more reasonable way to break them up, the writing is blatently lazy here. Like i can understand this being a boundary for someone but her character didnt portray any of those ideals beforehand, they literally just started hooking up randomly. Usually i wouldnt be so shocked about a p*rn manga having bad writing but i actually enjoyed the story for the first few chapters, regardless i still think the story is fun but i had to throw my 2 cents in for this one.
