The anime started off pretty great, but as the show went on, there was absolutely nothing happening.
This is an "semi-Isekai" (Reborn, but in the same world), and the king is reborn as a waifu. I thought there were be more comedic moments with this, but nothing came out of it. On top of this, the main character is a battle junkie with 0 character growth by the end.
I kept watching hoping for something interesting, but as the show dragged on, every episode became more painful and boring to watch. I'm a pretty positive Isekai reviewer who's at least enjoyed the bad Isekais as well. But unfortunately, this Isekai is not just bad, but its painfully boring.
I wouldn't recommend watching this one, even for heavier Isekai/Semi-Isekai/Fantasy fans. There are so many good shows out there to watch, and you get absolutely nothing out of this one.
