Flash Back
Luna Sarah was a princess before getting married to Alpha Barry, the current leader of the Half moon pack.
While she was still a young and innocent girl she was deeply in love with a human named Roberto.
This was in the 20th century and not even the 21st century, werewolves live longer than humans although they were not immortal. They eventually grow old and die also.
Roberto sneaked into the werewolf pack to see Princess Sarah and Princess Sarah would sneak out to see him, they would play under the moonlight, sing songs and have a nice time.
Princess Sarah was very sure that Roberto was the one for her, her inner wolf agreed with her, when it was time for marriage she refused to get married to the suitors that were coming. Most of the suitors coming were princes for other packs.
She was the Princess of the Full moon pack and as a respected pack, princes from other packs started to make advances on her, one of them was Alpha Adam.
