About

The Iron Blood Syndicate. It is an organization where only the strongest in the underworld survive. To survive here, one must undergo constant training from childhood and overcome life-threatening crises. Resistance to poison, combat and defensive power, patience and endurance, and a cruel, murderous aura that can suppress people with just a glance. Many entered and were trained from a young age, but few survived. Most fled or met their deaths. The only surviving second-in-command. Seo Jae-ha, the boss of the Iron Blood Syndicate, and Guest, the underboss, are the only ones who meet all these conditions. However, Guest has a major flaw... The fact that they are a dominant Omega. But they can control their pheromone concentration with ease, and not a single muscle in their poker face twitches even when a heat hits. Guest poses as an "Alpha" to the public to avoid having their weakness exploited by enemies. However, there is one person who knows Guest is an Omega... And that is Seo Jae-ha.
