Hello everyone! After much lurking I decided to join you for the read-along of this book club after all, even if a bit late. So for catching up:
Page 13
When 田山 says:
頑張ってお上品でいてね
Is this simply an encouragement like:
do your best (getting closer to 山田) and be/stay refined/elegant
Or is there possibly a hint of sarcasm as implied by this answer on HiNative?
I’m not even sure if refined/elegant fits as a word choice here, but that seems to be the most likely meaning going by the majority of results that come up doing a Google (image) search for お上品.
