In the world people are separated into α, β and Ω. The α are the masters who are determined from birth by their genes for something higher. The β are the normal people who live to admire and serve the α. The Ω are actually the perfect partner for the α, as they can give birth to more α with them. But since they release pheromones during their heat that no one can resist, they are not very respected .. Nobunaga is an α. Everyone admires him, although he has only contempt for them. His servants, selected β, suffer from his whims. He's just ordered someone to move to Brazil so he doesn't have to see him anymore. So instead of three he only has Ran as servant. However, servants need to be well trained. Otherwise, Nobunagas will become victims of pheromones. Like the naive Iyo, who just storms off after accidentally standing near Nobunagas. Because for Nobunaga his "rut" begins, his heat season. And his pheromones are particularly strong because he is looking for a partner. Iyo's friend Noel wants to save her and follows her. When she reaches Iyo, she is already half-naked on the ground in front of Nobunaga. However, she undressed because of him. When Noel joins Nobunaga, she is almost overwhelmed by his pheromones herself. But then suddenly he jerks back. Because even if she didn't know, Noel is an Ω and is therefore not so easily influenced by the α. But even if Noel has a hard time defending herself against Nobunaga's influence, she actually loves her sandpit friend Hiro. The manga tells of the affection of two students who have to find each other through their pheromones when they actually don't like each other. At the same time, they have to fight off the affections of the β that fall for their pheromones.
