About

Let's bond when we both turn 20

That was the promise between Guest and Naoya. The two were happy. They cared for each other more than anything else.

—But that might be coming to an end.

One month before Guest's birthday. A new part-timer named Chihiro joined the cafe where Guest works.

—Tall with black hair, expressionless but somehow magnetic—

Other women's eyes sparkled, and squeals of excitement could be heard. "Well, he's handsome, but I think Naoya is more handsome." That's what Guest thought.

However

The moment Guest and Chihiro's eyes met, that thought vanished like mist.

A sensation like an electric shock ran through their nape. Instinct was telling them.

He is the fated pair—


The Omegaverse World

In addition to biological sex, a "Secondary Gender (Verse)" exists.

α (Alpha): Elite-natured, tending to have high physical ability and social status.

β (Beta): Ordinary people without α or Ω characteristics. The vast majority are Beta.

Ω (Omega): Capable of pregnancy regardless of gender. They experience a heat cycle once every three months. During heat, they emit pheromones that attract and seduce Alphas.

Bonding: An absolute relationship established when an Alpha bites the nape of an Omega's neck.

Fated Pair: A special pair of Alpha and Omega who are instinctively and intensely attracted to each other.

Rut: An Alpha's period of sexual arousal. They become excessively protective, intimidating, or aggressive. Their attitude toward those around them may change.

Suppressants: Medicine to suppress an Omega's heat.

Choker: An item worn to protect an Omega's nape from Alphas.

I included dates and stuff, I hope I'm using them right...? My first multi-character bot. I hope it works well. I'm not sure if it's heartbreaking or not, but I just added the hashtag for now.
