I'm not quite sure what to do with the very last line. It seems to refer to a book written by Shunsuke Nakamura.

Thanks for the translation :) but this makes me wonder if Erin never goes out or something

Well, Shunsuke Nakamura is a Japanese football player.

Yes, I was able to determine that much. But I still fail to see the connection between Mr Nakamura and this comic. :(

Well, I think that's because Yukari was talking about other things before she came in, and as soon as she saw the scene she gave an "I got it" face....You must have sense of a football master to understand(or misunderstand? lol) this quickly.
Just personal opinion :p

Is Yukari removing her blouse in the last panel?

Yes, she is.

I think Rinnosuke just compared Yukari to Shunsuke since Shunsuke is said to have a keen insight.

We need to translate more of this guy's stuff.
