I'm glad I wasn't the only one who noticed how Nagatoro so casually altered the context of the article she had read, from "your man" to "a man"; and Paisen didn't react to that at all! He only reacted to what she's doing, and not why she was acting upon such an article. Her attempts to grab his sleeve reminds me some of chapter 2 of the Nagatoro-san doujins. At this point, these two are unofficially dating, they just need a bit more peer pressure to recognize it. With the lewdness in this chapter though, I think they may have skipped a few steps.
