Shinai naru Omega e

Mio Karino works as a dedicated secretary under his young master, Keisei Nagao, a man who harbors a deep-seated disdain for omegas. To maintain his position and avoid his employer's prejudice, Karino carefully conceals the fact that he is an omega himself. Despite Keisei's inherent distrust of others, Karino's unwavering devotion gradually breaks through his emotional walls, leading the guarded young master to open his heart in return. However, their fragile bond shatters when Keisei finally discovers Karino's hidden secondary gender. Feeling betrayed by the very person he had begun to trust, Keisei immediately orders his secretary to leave him forever. Driven away but burdened by personal circumstances that make it impossible for him to simply walk away or return to a normal life, Karino faces a desperate crossroads. Unwilling to lose the man he loves, he resorts to extreme measures, using suppressant drugs to forcibly mask his omega nature so he can find his way back to Keisei's side at any cost.
