A dialogue from 『狼と香辛料』


> ロレンス： 俺、いや、俺達は商人だ。儲かれば何でもいい、笑うのは金が入ってから、泣くのは破産してからだ。そして俺達は笑うんだ。
>
> ホロ： ああ
> すっとした。ま、ここ数百年まともに会話しとらんのじゃ喜怒哀楽に脆くなっとる。これでぬしの前で二度泣いたがな、ぬしの前でなくても泣いたじゃろう、何か言いたいか分かるかや？
>
> ロレンス： 勘違いするなと
>
> ホロ： うむ
>
> ロレンス：
> 俺も稼ぎのために相手してやってるんだからな。ミローネ商会が話を持ち掛けてくるまで逃げることが俺達の仕事だ。その最中にめそめそされると、足手まといになる。だから泣いてるのがお前じゃなくても、俺は…
>
> (ロレンス sees ポロ's cunning smile)
>
> ロレンス： お前…ずるくないか (conversation interrupted; new scene)

I think I understand everything in this dialogue except why ロレンス comments that
ホロ is ずるい. The 役割語 and style of speech are clear; so is the story context.
ホロ's 口癖 and 語尾 are uncommon and somewhat difficult but don't really affect
comprehension.

ロレンス comforts ホロ, telling her she shouldn't be sad that she is no longer
needed by the villagers, and then says "We are business people, so we only cry
when we lose money." (paraphrased) But I am not sure what happens in that
moment when their eyes meet and ロレンス notices a crafty grin on ホロ's face. Why
is ロレンス embarrassed in that moment? What does ロレンス say in the line immediately
prior to that moment that could be the reason?

This is from the anime, so there isn't any descriptive text. Also I
unwittingly cut the last line 「ん、雌の特権じゃろ」from ホロ. In order to avoid
contradicting @cats' answer (@cats' answer mentions "your last line"), I will
leave that line here.




To supplement @cats's answer, I'd also like to take a look at how this scene
plays out in the anime.

In the anime, Lawrence says だから泣いてるのがお前じゃなくても、俺は but stops himself mid-
sentence when he sees Holo's reaction:

[![Holo looking slightly hurt by what Lawrence
said](https://i.stack.imgur.com/BdonS.jpg)](https://i.stack.imgur.com/BdonS.jpg)

A somewhat judgmental and not too happy expression (in the light novel she is
described as looking hurt by what he said) -- which elicits お前、ずるくないか from
Lawrence because while he took her ぬしの前でなくても泣いたじゃろう in stride, when faced with
this expression he probably can't help but feel a little bad. And then it is
in response to his slightly troubled reaction that she brings out a cunning
smile a few moments later.

For reference, here is [how this scene plays out in the light
novel](https://i.stack.imgur.com/PBPvt.png), in which one gets a better sense
of how this is really just a lighthearted back-and-forth between the two of
them.




At least from the one source I could find, there are some supplementary lines
that may clarify things.

> だから俺の前でないてるのがお前じゃなくても、俺はーー
>
> と、その先のロレンスの言葉は出なかった。
>
> ホロが傷ついたような顔をして、ロレンスの方を見つめていたからだ。
>
> 「・・・・・・お前、ずるくないか」
>
> 「ん、雌の特権じゃろ」
>
> いけしゃあしゃあと言うので、ロレンスはかるkホロの頭を小突いたのだった。

At this point they're basically flirting... She's trying to act like she would
cry in front of everyone because she hasn't had a real conversation in a long
time, so he isn't special, and he's trying to act like he would comfort anyone
crying in front of him, using the "crying doesn't make money" line, so she
isn't special. She acts hurt, he says your last line (which should make sense
now), and so on.
