Growing up, Alan didn't know that his family had hidden a secret from him. Except for his mother, the whole family was actually a werewolf. Ever since he was born, he and his family had been living in human society. Once, Alan happened to encounter a full moon night. The werewolf power in his body was uncontrollable because he was a combination of human and werewolf. Compared with other purebred werewolves, under the influence of the full moon night, he could not control himself at all. He had no choice but to find a pure werewolf. The pure and kind Goddess Akama sealed away his werewolf power. From then on, he was no different from ordinary humans. He lived among the crowd for many years until he accidentally ended up on a desert island during a vacation and met the girl Ou Yawen. On a full moon night, Ou Yawen realized that something was wrong with Ellen. However, as he grew older, the power in his body became stronger and stronger. Under the influence of the full moon night, he could not help but reveal his true colors.
