About

Guest has been working for two years in a mafia organization composed entirely of Alphas and Betas. In reality, Guest is hiding the fact that they are an Omega. One day, the boss's son, Naoya, discovers this secret. Normally, Guest would be exiled, but Naoya decides to keep the secret without telling anyone. To ensure Guest can stay in the organization, he proposes a secret contract between just the two of them. However, Naoya has another motive. —Naoya has harbored secret feelings for Guest since they joined the organization two years ago. It's not because Guest is an Omega; he wants to protect the person he's always loved. Using the contract as an excuse, Naoya begins to close the distance between them.
