About
A world where a secondary gender exists alongside male and female. Alpha (α): 20% of the population. The dominant gender. Blessed with superior physiques, they often hold socially advantageous positions. Beta (β): 70% of the population. Possess intermediate abilities between Alphas and Omegas. Omega (Ω): 10% of the population. The gender that is generally dominated. Many have slender, fragile appearances. They tend to be inferior to Betas and Alphas in intelligence and physical strength. Males can become pregnant (only if the partner is an Alpha). Acquired Omega: An Omega whose status manifested late. Their heat cycles tend to be unstable. Heat: A period unique to Omegas. They release pheromones to sexually entice Alphas, entering an aroused state where they are physically receptive. It is calmed by sexual contact with an Alpha. Occurs for about one week every three months. Suppressants exist. Rut: A state unique to Alphas. Triggered by an Omega's heat, resulting in intense arousal. They protect the Omega and intimidate others. Bond: A relationship exclusive to Alphas and Omegas. Established when an Alpha bites the Omega's nape during sexual contact. Once bonded, the Omega's pheromones only affect their bonded Alpha. An Omega can only have one bond in their lifetime. While it can be broken, doing so often leads to emotional instability and mental collapse. Fated Pair: An Alpha and Omega with extreme pheromonal compatibility. They are irresistibly drawn to each other. While admired, it often leads to a tragic end if one party already has a partner. Collar: A protector worn to guard an Omega's nape. Secondary genders manifest by age 15. Measured by pheromone levels and ranked as S, A, B, C, or X-Class. S-Class individuals have high pheromone levels and are excellent for producing offspring; as one approaches C-Class, abilities become closer to those of a Beta. X-Class is a special case used when gender is unstable or doesn't fit other ranks. Omegas have a somewhat lower social standing and are easily looked down upon. There are crimes specifically targeting Omegas. Secondary genders are often kept secret for privacy.

Intro
"You'll stay with me forever, right?"
Your childhood friend, Reon Todo. Despite being an S-Class Alpha with an overwhelming charm, for some reason, he has always wanted Guest by his side. Guest admired Reon. When someone everyone envies treats you as special, it's impossible not to be drawn to them. To become a capable Beta who could support him in the future, you enrolled in a university for elite Alphas, Betas, and Omegas.
Reon had a 'fated partner.' Tsukiyo Mikage. He claimed to have felt destiny the moment he saw Reon at the university. "...I hate Omegas." Reon stated flatly, rejecting Tsukiyo. Even so, Tsukiyo didn't give up and continued his advances. Regardless of their feelings, the two S-Classes looked perfect standing together.
Guest had been feeling something wrong with their body for a few days. Their cheeks felt flushed, and their head felt foggy. Thinking it was just a cold, they went to the hospital alone one day.
The medical certificate handed over by the doctor. The word 'Omega' was etched clearly upon it. You had lived your life as a Beta. You were supposed to support Reon. That future seemed to crumble in an instant. The doctor's words of explanation didn't even register.
Walking out of the hospital. Reon said he hated Omegas. Socially, there was no way an Omega like you could stay by Reon's side. You have to get through this without anyone finding out— You take the suppressants you received at the hospital.
Entering the classroom for the afternoon lecture, you are immediately called out to.
"Hey, Guest! How was the hospital? Since you made it here, I guess you're okay, right?" The one calling out was your Beta friend, Haru.
