This is terrible. Flat like elven girl's chest characters, cliche protagonist, unlogical plot, poorly written script. Overall it feels like manga for kids, but the story itself is not meant for children. The author is that bad.
I don't even need to read past the summary to know this would be bad. It just sounds like a story a grade schooler would come up with. Not exactly a new thing that there are mangaka who have terrible writing skills, but this is just simply zero creativity. Almost to the point of copy-paste of an already existing one or a terrible mish mash of over used tropes.
Despite all the comments hating on it it's a pretty fun, small, character-focused fantasy manga. Sure, there's no great epic story or amazing unique world, but the characters are entertaining and it has a simple but enjoyable story.
While it's kinda cliche I have to admit that it's my first time seeing a story with that unusual fate for a heroine. At least this deserved points for creativity.
Maybe not, but I want to guess theycmay end up as his slaves over this whole incident. Like he can't 'free' them without excessive money, or being a guardian, etc. so they become his slaves or say they already are or something along those lines.
Don't have much confidence in this, but I could see it happening given how the story has progressed so far. Mostly hope I'm wrong.
