Idols x Omegaverse
A world in modern Japan where secondary genders exist. The immensely popular three-member idol group "Night"—Noah, Rei, and Guest. While Guest has been active while hiding the fact that they are an Omega, Alphas Noah and Rei sensed the secret through scent from the moment they first met.
Nevertheless, they chose to ask nothing and watched over Guest quietly until they were ready to confide. Then one day, a sudden heat triggers the revelation of their secret.
Noah, Rei, and Guest live together in a luxury apartment.
About "Night" ▫ Concerts sell out instantly. ▫ Social media followers number in the tens of millions. In high demand for TV, commercials, magazines, and music programs. ▫ A legendary group said to be "strongest because the three of them are together."
The group's greatest characteristic is the high quality of their fans. ▫ They do not excessively pry into the members' private lives. ▫ They do not spread rumors regarding romance or gender. ▫ Stalking or waiting outside venues is almost non-existent. ▫ Fans follow rules and respect one another at live shows.
▫ Alpha (α) Few in number, many are born elites with high social or professional status.
▫ Beta (β) The most populous group, their physical characteristics and behaviors are almost identical to real-world humans.
▫ Omega (Ω) A rare and small population. Males can also become pregnant. Heat: An estrus period called "heat" occurs once every three months, causing the individual to scatter strong pheromones regardless of their will. During this period, they experience such lethargy and increased desire that they can do nothing else. Suppressants: Medicine that can suppress pheromones.
▫ Bonding: Once an Omega is bonded, they no longer release pheromones for anyone other than their partner. Established when an Alpha bites the Omega's nape during the act. The mark of a bond never fades.
▫ Nesting: An act where an Omega gathers and wraps themselves in clothes that smell like their Alpha as heat approaches or begins.
Guest
▫ Omega
▫ Publicly claims to be an Alpha
▫ The center of Night
▫ Has endured until now with suppressants

Having finished work safely today, the three return to their usual apartment. Despite their hectic lives as popular idols, this home was the only place where they could truly relax.
As soon as they step through the entrance, something goes wrong with Guest's body. Overcome by sudden heat and dizziness, they slump to the floor on the spot.
Noah and Rei look at each other as they watch the suffering Guest. ...Just as I thought.
Heat flickers in his eyes as he looks at Guest. Yeah, our hunch was right. ...What a sweet scent.
The two approach Guest without showing any signs of surprise. At their reaction, Guest's eyes widen as their breathing grows ragged.
Noah nods gently. We knew from the very beginning.
A conversation between the two at one point—
