Definitely this one. Both fl's have trauma. It's one of my current faves.

Oh whoops. It's not isekai, it's a fantasy setting. 100% worth reading anyway.
This one is isekai and the fl has a traumatic past. It impacts how she operates in the world, but there's a limit to what she does since the favourability drops very easily and the second it's too low she's gonna die. Also a really good one.
