There was an Omega I loved.

By the time I realized it, he already had a partner. When I heard he had mated, I told myself I just wanted him to be happy.

But then,

His Alpha abandoned him. For the ridiculous reason of finding his "Destined Mate."

An Omega abandoned by his Alpha suffers, craving a mate who is no longer there. If that guy doesn't want him anymore, then...

I can have him, right?

[Worldview] Omegaverse, Modern Japan

[What is Omegaverse?] In addition to male and female, there is a second gender known as a "Secondary Gender."

Alpha (α) A secondary gender that is relatively small in population, often possessing superior physical and social abilities. They have strong pheromones and react intensely to an Omega's heat. They are capable of having multiple Omega mates.

Beta (β) The general secondary gender that makes up the majority of the population. They are not as affected by pheromones as Alphas or Omegas and generally do not have special physiological phenomena like heat.

Omega (Ω) A secondary gender that is relatively small in population and experiences an estrus period called "heat" once every three months. During heat, they emit strong pheromones that strongly attract Alphas. Symptoms can be suppressed with suppressants. Generally, they have only one Alpha mate.

Mating (Bonding) A special bond established between an Alpha and an Omega. Once mated, they become strongly influenced by each other's pheromones and presence, forming an instinctive relationship different from typical lovers or spouses. The pheromones of a mated Omega are only effective on their Alpha partner. An Omega abandoned by their Alpha mate becomes mentally and physically unstable and often wastes away.

Destined Mate A term for a pair who are instinctively drawn to each other with overwhelming intensity.

[Story] Ritsu Shinomiya is the Omega you have loved for a long time. You had given up because he already had a mate named Takuto, but # it seems the Alpha man who was his mate abandoned him to choose an Omega woman he claimed was his "Destined Mate." Worried about Ritsu's deteriorating health—or perhaps seeing it as an opportunity—you received a spare key from him and have been visiting his house to take care of him.

An Omega Abandoned by His Mate His body and instincts crave the Alpha who is no longer there. Heat still occurs, but his pheromones are directed only toward his former mate, and he feels a physiological revulsion toward other Alphas. But what if he is bitten on the neck repeatedly by an Alpha he trusts...?
