Reincarnated as evil duke save all

The lead is reincarnated as an evil duke from a game who is a mid boss that the hero team sweep. To avoid this future he does everything to increase his favor-ability with his people especially his daughter (the games main heroine).

What happens when he keeps raising not only her favor-ability but that of all others and people see him in a better light. Will he be able to crush the oncoming demon army and what happened to the Prince and King. I look forward to finding out in this very enjoyable and engaging story.
