For people who are still confused, this is Obie_chan’s comment explaining. Their comment is replied below Sallie’s comment. I’m sharing here just in case peeps dont want to scroll down to and search for it.

“The main character's father was the younger brother of the family head(the one who spoils Aoi). The father was a mistress to a god dog as well like the older brother(family head) and Aoi's new dog lover. Since the father decided to leave the dog god and make a family, when Aoi(mc) was born, the dog god went on rampage mood and killed off Aoi's family and his old lover. Aoi blames himself because if he wasn't born, the dog god wouldn't have probably went on a killing spree.

also they say Aoi has dog blood because before his father's dog blood disappeared, Aoi was born while his father was part dog.”
