Heya! How much has Ziya been ~out and about, during or after her marriage? I feel like she and Francesca might get along as friends but there's a bit of an age gap and Francesca isn't heavily invested in society, so Ziya's husband's abuse extended to restricting where she went or who she could talk to then there may not have been many opportunities to interact. But if he didn't care where she went (or if she started getting out more after he died) they could maybe have met over books at Crowdy or something along those lines.
