is this good???

yes

is it a harem?

The ML has one but the girls are total badasses and they’re more like his bodyguards

yes to add on to what @elisamartz said, the harem is also for political and fighting purposes, so its not at all romantic basically. there would only be one female he ends up with romantically in the end

so the girls in his harem doesn't like him?

no, except one tho, although ML doesnt pay attention to her so no worries
