Moonlight (l.S) a/b/o

Ever since Louis was born he always knew what his future would be: mating Harry Styles and unite both Tomlinson and Styles packs, the biggest and most powerful packs in England, creating the Diamond Pack. His mother the Luna and his father the Pack Alpha always made sure to remind and taught him to be a good alpha and omega, whichever he would present as when he turned 16. Louis liked the alpha idea more than being an omega, and prayed to the moon goddess to be an alpha. Shortly after he was born he was assigned a "pearl" who would be always by his side as his maid. His name was Niall, a blonde omega, that was the same age as Louis.
Will Louis be an Alpha or Omega? Will he accept his mate? Will they bond?
