Alpha's Rejected

Takuzou Shouji is a 17 year old, "Aqua Shifter". An aqua shifter is a cross between a mermaid/merman and animal shifter. Their upper parts are human, but their bottom half's are the tails of a shark, whale, or dolphin. When Takuzou and his pod move to America, they live next to a werewolf territory, but the school is on neutral ground.
On his first day, of school Takuzou run's into Trevor Darkhart, Alpha of the Dark Moon Blood Pack... and his mate.

Trevor, thinks that Takuzou is a human and because he is not gay, he rejects his mate. He didn't expect his ex-mate to accepted the rejection.
