Is this は contrastive?

I'm unsure how to interpret that は in that part of the sentence. I'm assuming
it's a contrastive は but I'm not sure what it's contrasting.

Thank you!




That wa is not really contrastive but anyway, in general, the particle tends
to be wa when the sentence is negation and ~~especially~~ when the word
doesn't feel really unexpected against the context to the speaker. To be
honest, either ga or wa are fine as long as the example sentence is concerned.

(As for the controversy about wa's essential role, If you support contrastive
wa fundamentalism, it is. If you support topic marker wa fundamentalism, it
is.)
