Another chapter wasted on that shameless whore, and she probably hasn't been more brazenly licentious than in this one. She already knows that Haruta is in a relationship. She never makes headway with him, despite constantly throwing her body at him, for one, and
he's always seen with one person. All this, and she can't put two and two together to get four?
Or maybe she can, she just doesn't care as long as she can get her walls parted.
Meanwhile, Haruta's putting as much distance as possible between himself and that Man Card he had to relinquish a little while back. It really doesn't make sense: he's not only been in multiple lewd situations with Mone-san, but the babysitting chapter made it all but clear that they were at least making out at the end. Why should he be so bothered by this tramp propositioning him? (It gives a whole lot of weight to your words,
@Acolytus, because if he remembered Mone-san, he wouldn't lose his damned mind over a slut.)
At this point, the only reason I'm still reading this manga is because of Mone-san. Rarely does a character like her--in terms of looks and character--get to be the focus of her own story without stupid flaws added (in this case, ostensibly--the author's trying hard to forget whose name is in the title, and what the story's supposed to be about). It's just a shame that these mobs, each of whose character archetypes/designs can be found as the focus of countless stories prior, are now hogging the story.
