The Hero is so yandere, I'm almost tempted to tag this 'Horror' for the maid's sake...
This manga also borrows alot of elements from RPG and game manga tropes, but it is not a game. Still, that might interest some readers, so worth mentioning.
As a romance shoujo this manga is just not for me. It romanticizes and ignores abuse and even trying to read it to see if the character/mangaka acknowledges those failings is beyond frustrating. It's clear the mangaka will not be giving the maid any agency over her own story or decisions and just continues to let the hero force her into a marriage she doesn't want, dragging her and the story along. The one character that was even willing to speak up against the hero (as he's too powerful and literally everyone else is too scared to go against him) was written off as weak and a creep even...
I had to stop shortly after the permanent magnet-GPS engagement bracelet was forced onto her wrist, because this just had too many triggers for me.
Trying to ignore all that, there's ALOT of exposition without any real action, making the panels more wordy than needed. For all that it's characters and premises are attempting to subvert the hero's love story trope, it is really not all that different plot wise from other basic romances arcs. It brings up some really neat ideas though which initially attracted me to the story, but ultimately I think the direction the mangaka went to tell the story was a poor decision. Which is a real shame because I would have liked to read about a mob character Maid find her confidence, to see the Hero believably find his emotions and new purpose now that his Hero's Quest was done. But this story gives us none of that.
The story is appalling, but the art is OK and there are interesting ideas and characters even if they're not put to use correctly in the story. 3/10
