“Theo Peserus”, the head of the household, had received an oracle to give birth to a child who would pass on to the family. As he always does to invite the other Alpha, he waits for his opponent that evening while lying on the bed with his eyes closed. In the quiet corridor of Peserus’ Castle, there was "Seram Marita," the Alpha of the Revolutionary Army who had been captured.

In the room, Alpha Theo, who had loads of pheromones like an Omega, was lying blindfolded on the bed. The strange pheromone intoxicated Seram, who lost his purpose and eventually committed to Theo. Seram was captured once more, but Theo saved him when he was about to be executed for escaping...
