I actually really liked this one!!
This one might be the best of the volume and totally has room for a series!
For example:
-She can extend her sight seeing for world building
-She's clearly loved by her territory, allowing for some possible side love interests
-The previous soul of Rina is still in limbo
-And that God!! They could totally create some conflicts regarding her soul
I think it'd be cool if the real Rina came back, either via 2nd child birth or getting her body back, but the mc now gets he own (homonculi?) body! The conflict between the bodies and who the ML really looks would also be an interesting plot point!
Mix it in with some other li's and you have some crazy drama!
And then there could be a sub-plot romance where the real Rina falls in love with a losing love interest!
Also the art and mc are super cute!! This artist clearly know how to shade and style their characters right!

Even the side characters had personality shown through how their face and clothes were drawn.
