I woke up in the body of mob character Civilian 1 in the "tragic novel" I wrote with my friends for fun. And since Duke Henstone, the father of the female protagonist, starts a revolution in order to change his daughter's unhappy future, many lives are in danger if I leave it like this. "I will protect the female lead!" That's how I started to live with the daughter of the stupid duke. But for some reason, the small female lead is a bit strange. "Why do you keep trying to hook me up with your dad?" Source: MU
