For a whole chapter dedicated to talking over a meal, this was pretty good! The conversation kept my attention.
Something about Gotou feels disingenuous, though. She seems really manipulative and a bit narcissistic. Her reasoning makes zero sense, as well. Saying something like: "I have a boyfriend I've been with for the last five years" is not 'pumping the brakes' on things -- it's a full blown crashing stop. Any normal and reasonable man would not only give up their pursuit, but also just as likely be kind of irritated as Yoshida was in Ch.1 when he said: "Then don't go on a date!".
She's really not looking good here either. Not only is she persecuting him for "what if's", but then further demonstrates her lack of trust by more or less demanding to personally inspect the situation. Essentially, rewarding all of the straightforward and honest behavior he's demonstrated when interacting with her with further suspicion; even after multiple reassurance's. She's the only one with a history of dishonesty here, and yet she can't simply trust him? Speaking realistically for a moment, is it really that hard to believe that an adult male in his mid-to-late-20's wouldn't be attracted to a 15 or 16-year-old high school girl? It seems much more believable than her with the whole"my spider-sense was tinglin" shit.
I just can't see that she's being completely open yet. Something about her just feels off. Even if on the surface she seems like the ideal woman, the Kouhai seems much more genuine.
