The Substitute Luna (Alpha King)

“The hero was the Alpha King's most remarkable son, the strongest werewolf fighter, and the heir to the Alpha King. The wolfsbane goddess of the pack had predicted that the hero would never have his mate, which became an obstacle for him to inherit the throne. Therefore, after the hero became an adult, the Alpha King organized a mating assembly every year to let all the mateless werewolves come to participate in the hope that the hero could marry a suitable werewolf, who was the future Luna. How is the next?”
