Interpretting 別に...とは無関係なところで


> 俺としては、姉についてはあまり触れられたくない話題だ。 **別に、姉の死を思い出すとつらい…といったようなセンチメンタルとは無関係なところで**
> 、余計なことを思い出して気が重くなるからだ。

Based on the statement ending with "余計なことを思い出して気が重くなるからだ", i would expect the
first half to have a soft "it's not that bad" nuance. (ie.
別に[姉の...ようなセンチメンタル]ではないだが、余計な...)

But I'm not sure how to read 別に[姉の...ようなセンチメンタル]とは無関係なところで in a logical manner
with that in mind.

thanks




「別に」is being used here with「無関係な」to indicate that something is "not
particularly related".

While you are correct that「別に」is often used in this way with the negative form
of verbs and adjectives, here the 形容動詞 「無関係（な）」already has a negative meaning.
In fact, if we were to further negate 「別に無関係」 to 「別に無関係じゃない」it would change
meaning from 「not particularly related」to something like「not necessarily
unrelated」.

So

> 俺としては、姉についてはあまり触れられたくない話題だ。 **別に** 、姉の死を思い出すとつらい…といったようなセンチメンタルとは
> **無関係なところで** 、余計なことを思い出して気が重くなるからだ。

becomes

> For me, the subject of my older sister isn't really one I want touched upon.
> **It's not particularly because** I get worked up about it **or anything** ,
> like that it's painful for me or something to remember her death, it's
> because it brings back memories I don't really need brought back and gets me
> a little depressed.
