After Being Kicked Out, My Sisters Begged for Forgiveness

Originally, the male protagonist had a bad life at home. He left home after his rebirth and thought about how nice someone in his previous life was to the male protagonist. Since he was writing about such a woman, why should he write about the woman's family's attitude towards the male protagonist being so bad? Isn't it obvious that he has been abused to death in his whole life? Do he want to be a licking dog in this life?
