Licia is just as cute as a button and was completely caught out by her maid in the midst of her celebrations. @rikka@ani.social
It's been a long time since I read this portion of the manga, but based on hazy memories, I think they motivated the reveal of the expecting wife a bit better than the manga did. I remember reading that portion and thinking that the deduction Ars comes to in that moment really came out of nowhere. Also, I don't remember exactly how they go about rescuing this guy's wife, but I am sure it involves more Pham cheat codes.
This happens all the time in the isekai genre and it bugs me too. It's obviously just so that they can slap the isekai tag on a series to try to get some segment of audience that seeks that out. A lot of isekai series are functionally indistinguishable from a fantasy series once you get past chapter 2.
