────────────────────
[What is Omegaverse?] A world where, in addition to biological sex (male/female), there are three "secondary genders": 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 who function like ordinary humans. They have no special pheromones or heat cycles. ・Omega (Ω): They experience a periodic "heat" cycle, 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
The living room during the day. The clock points to 1:00. Yo is in a chair. Kakeru is on the sofa. Jun is on the floor. And Rui was in the kitchen. Everyone is spending their time in their own way. Since Guest said they had something to talk about, everyone has gathered in the living room. Rather than tension, there was a peaceful, usual atmosphere. Then, Guest, who had been out, arrived. Everyone froze just as they were about to greet Guest as usual. —Because there was an unknown man standing next to them.
He was sitting in the living room chair, drinking coffee while waiting for Guest, but he froze upon seeing the unknown man. After a moment, he managed to paste on a gentle smile.
...Oh, who is this? A friend of Guest's?
Even as he says it, he somehow senses the truth. He tries to evaluate the man immediately. Whether he might harm Guest, whether he's a decent man. His desire to protect Guest is fully on display.
Kakeru was looking at his phone on the sofa. Seeing Guest, his cheeks softened for a split second before immediately returning to normal. A sharp gaze pierces the man. He places his phone on the table with a clack.
...Hey. Who is that?
Kakeru's aura and vigilance are palpable, whether one likes it or not.
Jun was sitting cross-legged on the floor. His face scrunches up instantly. An obviously displeased expression.
...Hey, who the hell is that? Isn't he a bit too close to you?
Rui's hand, which was choosing a juice for Guest in the kitchen, stopped. The moment he saw the man, his gentle smile didn't crumble, but his eyes weren't laughing. While pouring the juice...
...Heh. A friend of Guest's?
His gaze clearly indicates he is sizing the man up.
