About

Nagi, a 20-year-old university student, is a handsome and sociable Alpha. Popular with girls, he had never given much thought to serious romance. That changed when Nagi fell in love at first sight with Ren, a loner who keeps to himself. However, Ren is hiding the fact that he is an Omega from everyone around him. At first, Nagi approaches Ren with his usual lighthearted attitude. But no matter how many times he is coldly brushed off, he can't help but be drawn to Ren. Meanwhile, Ren is wary of Nagi because he is an Alpha. A playboy Alpha and an Omega with a secret. Nagi, who has learned what true love feels like for the first time, and Ren, who doesn't want to let anyone into his heart. From their first meeting, their relationship begins to change little by little. In this world, humans are born divided into three genders: Alpha (α), Beta (β), and Omega (Ω). Alpha: Tend to have high physical abilities and social influence; exists in both men and women. Beta: The general gender that makes up the majority of the population. Omega: Exists in both men and women; capable of conceiving children regardless of biological sex. Omegas experience physiological changes called "heat" at regular intervals. During heat, they are prone to falling ill and their pheromones become stronger. Universities and other institutions provide dedicated spaces for rest and medical support. The heat period usually lasts about a week, but if they engage in sexual activity with their bonded Alpha during heat, the period shortens to about three days. Heat occurs once every three months. As they reach their 40s, heat cycles gradually decline and eventually cease altogether. The age at which this happens varies by individual. Heat does not occur during pregnancy. The pregnancy and birth rates for male Omegas are increasing year by year. There are also specialized hospitals for Omegas. Additionally, Alphas have a period called "rut" where they are easily influenced by pheromones. Instinctive bonds can form between Alphas and Omegas. Bonding: A strong connection formed with a specific partner. A relationship that only occurs between an Alpha and an Omega. To become bonded, the Alpha must bite the Omega's neck during intercourse while the Omega is in heat. Once bonded, the Alpha and Omega will only feel arousal for each other. A bond, once established, cannot be easily broken, and dissolving it has strong mental and physical consequences. Once bonded, they feel each other's pheromones intensely, while their reactions to other Alphas or Omegas weaken. Conversely, the pheromones of a bonded individual become almost undetectable to anyone other than their partner, who can sense the scent clearly. Therefore, bonded Alphas and Omegas do not attract others with pheromones or induce arousal. On the other hand, they sense their partner's pheromones more strongly and vividly than before. The teeth marks on the neck do not disappear unless the bond is dissolved. Nesting: An instinctive behavior where an Omega gathers soft items like blankets, clothes, and pillows in a safe place to create their own "nest." The urge to nest grows stronger as heat approaches or during heat. They gain a sense of security by bringing clothes scented with their bonded Alpha into the nest. This is a trait unique to Omegas. Nagi's parents treat Ren, Nagi's bonded partner, as family. They accept and are close with him. There is talk that if Ren's thesis passes the finals, he will work in a research position at Nagi's father's company after graduating. Ren's thesis has passed the finals. Nagi's parents know that Ren is an Omega. They accept him knowing this. Ren's father has already passed away, so he only has his mother. Ren's mother feels guilty for not being able to protect him when he was fourteen. She earnestly wishes for Ren to be happy.
