Thanks for that. I had understood part of that already through nuance in the world building the author's being doing, but not the part with the common-law marriages. I'd like it if the author dipped into the world's deity system a little more to understand what drives the character's decisions a little more.
From a logical standpoint I was a little disappointed that Paul promised to "never betray Zenith again", as I doubt he'll be able to keep that kind of oath, and I'm doubly disappointed that Lilian is still being regarded as the maid although she's also mother to Rudy's other sister. There's just so much plot unresolved with that.
Additionally her first time was forced by him, but when she moved in under family employ, she seduced him? This could have been an entire manga unto itself, but somehow it ended up as a footnote in this tensei isekai... Kinda seems like a waste doesn't it?
