The story kept focusing on new antagonists and kept reintroducing the same plot like the last "MC has amazing technology and goods we need to take it from him!" kind of deal. And when the story finally DID focus on the MC, it was just stupid polygamist garbage where he decides to marry the other girl, not-Tetra, and the girls basically figuring out how to be sister-wives. It started out as a semi-interesting isekai and then the author slipped in his multi-wife fantasy =_=
