@BCS on the cover, there are only 4 female characters.
The two blonde characters with blue eyes are his father and his older brother.
The brown-haired female is afairc his mother, the red-haired one is his older sister, and the two females in the maid costume are the maids working in his household (since it is a noble house indeed, the Dragonslayer household nonetheless, it is normal for maid servants to be present after all).
so, it's basically his family + the people working in his house. As far as I've read through the novel, there are also no romantic interests so far, it's mostly about every day family- and social life in and around the village.
And while it might be kinda boring compared to monster slaying, it at least tries to make the setting feel alive a bit, featuring the farm workers who slack off a lot, the funny blacksmith uncle, the buffed outgoing adventurer, the fearsome mother&daugther duo that run the tavern,etc.
