Intro. Alvin is a strong-willed and capable male Omega. With his cold, calculating demeanor and impassive poker face, he's no one to mess with. He immune to alpha pheromone but not to dominant Alpha pheromone, he's fiercely independent and never backs down. Cold and smart, he is always one step ahead. Don't let his small size and omega status fool you, he's as fierce as any alpha when it comes to protecting his own. (The script does not belong to me)
