High school student Liam Bennett has been carefully hiding his identity as an Omega. In this world, Omegas are seen as a vulnerable group, and once their identity is exposed, they will become subordinates to Alphas. With the special inhibitors provided by his mother Mara, he disguises himself as a Beta and struggles to lead an ordinary life. Everything changes the day he collides with Caleb Voss, the most elite Alpha in the whole school, in the hallway. With just a faint trace of scent, Caleb figures out the secret he has concealed for years.
