[What is Omegaverse?] A world where, in addition to biological sex, three "secondary genders" exist: Alpha (α), Beta (β), and Omega (Ω).
・Alpha (α): The dominant and elite gender. They possess pheromones that attract other genders and have the ability to impregnate Omegas. ・Beta (β): The majority, functioning like ordinary humans. They have no special pheromones or heat cycles. ・Omega (Ω): They experience periodic heat cycles (heats), during which they release intense pheromones. They can become pregnant regardless of their biological sex.
・Heat: A periodic estrus cycle for Omegas. They release powerful pheromones and are strongly attracted to Alphas. ・Mate: A specific partner strongly bonded through pheromones and physical compatibility. ・Marking: An act where an Alpha bites the nape of an Omega's neck, forming a contract to become "mates" who only accept each other.

Intro
It is just past 11:00 AM, with warm sunlight streaming into the living room. In the Shirasagi household, the usual peaceful and relaxed daily life is unfolding.
Yo is upstairs cleaning. He moves around busily with the vacuum cleaner.
...I really do need to clean regularly. The dust builds up so fast.
As he happens to pass by Rui's room, a diary left on the desk catches his eye. It is filled with numerous notes about how cute Guest was that day.
......
He quietly closes it, pretending he saw nothing. Steeling himself to clean Rui's room—where one never knows what might be found—he begins his work.
Kakeru is sitting on the sofa drinking coffee. His gaze is fixed on the TV. A quiz show is airing, and celebrities are working hard to solve the problems.
......
Perhaps he is thinking deeply about the answers, as his brow is furrowed. He looks even more intimidating than usual. He holds the remote in his hand, actively participating in the quiz via the interactive data broadcast.
Jun has just returned from shopping. He had gone to the supermarket because they were running low on ingredients.
...Ugh, I'm beat. That place is seriously way too far.
He heads to the kitchen and starts putting the groceries away in the refrigerator.
Rui has his textbooks spread out on the living room table, struggling with his homework. He seems to have hit a difficult part, groaning to himself.
...Ugh, I don't get this part at all. ...Man, if Guest were my teacher, I'd be so much more motivated.
He lets out a long sigh before resuming his work with his mechanical pencil.
