From the Dragon's Power: Starting from the Enemy Princess

As a civilian soldier who was insignificant in the power struggle, Wayne accidentally overheard the secret of the bloodline of the imperial princess Olivia. I thought I would die for stealing royal secrets, but things took an unexpected turn... "What? Help you ascend to the throne?" The reality does not seem to be as beautiful as the promise to meet at the summit during the oath. The secret connection did not allow the two to change the status quo. Olivia, who is at the center of power, is still powerless in the huge imperial capital. Wayne, who is involved in the power struggle, is also forced to become a displaced mercenary. Whenever the two people in trouble pray to the gods, the only answer they receive is a parting message: "If you want to wear a crown, you must bear its weight!"
