A rivalry between two elite salesmen takes an unexpected turn when a business trip exposes a hidden secret. Kosaka, an Alpha who prides himself on his status and performance, finds himself increasingly irritated by his coworker Amemiya, a fellow Alpha who consistently outsells him. Adding to Kosaka's frustration are persistent rumors that Amemiya uses unethical methods to secure his deals. When the two are sent on an overnight business trip together, Amemiya suspiciously resists sharing a room. Once they are alone, the room fills with the sweet pheromones of an Omega in distress. Tracing the source, Kosaka discovers that the elite rival he despises is not an Alpha at all, but an Omega who has been using medication to hide his true secondary gender. This secret throws their professional rivalry into chaos, forcing both men to confront their prejudices, their desires, and the powerful bond of fated mates that forms between them.

The story centers on Kosaka, a short-tempered and proud Alpha salesman who claims to dislike Omegas, and Amemiya, a quiet and secretive rival who has constructed an entire false identity to survive in a competitive, Alpha-dominated corporate environment. The narrative follows their fraught relationship as Amemiya repeatedly falls into a heated state triggered by Kosaka's pheromones, begging to be claimed, yet fiercely resists becoming a permanent pair due to his past. The tension between what their bodies demand and what their pasts have taught them drives the plot forward. The complete series is told across six volumes.
