Lottery System Dad: Hearts to Win, Fate to Rewrite

It is a famine year in an ancient dynasty, and in one house five girls are waiting for their father to die. The father is a man hated by people and gods alike. Adrian Lee wakes up inside that man's body, in that year, with those five daughters to feed. A lottery system opens for him. The girls' affection is counted in points, the points can be spent on supplies, and the prizes get better as the count rises. He feeds and looks after the five, the points come in, and the children in time accept him as their father. The household settles into a comfortable life. Then the mothers of the five girls begin turning up at the house, one after another, and each of them has a background with enough power in it to shake the empire.
