Natsume Oga is a celebrated actor who has been in the spotlight since childhood, but he harbors a secret that could destroy his career: he is an Omega. In an entertainment industry that demands perfection, Natsume endures his difficult heat cycles alone, hiding his secondary gender from the public who believes his talent must mean he is an Alpha. His only source of comfort is his longtime friend and fellow actor, Kotaro Chitose, a warm-hearted Beta. After Kotaro inadvertently discovers Natsume during a heat episode, he becomes the actor’s sole emotional support, offering a safe and non-judgmental presence despite knowing that as a Beta he cannot fully alleviate Natsume’s physical suffering.

The story explores the evolving relationship between an elite, hidden Omega and a Beta who feels inferior due to his own secondary gender. As Natsume struggles to maintain his distance and protect his secret, Kotaro refuses to abandon him, choosing to remain by his side even though a traditional pair bond is impossible between them. The central conflict questions whether a love between a Beta and an Omega can truly flourish when society expects Omegas to bond with Alphas. Their bond deepens against the backdrop of the entertainment world, where they must navigate the pressures of public scrutiny, demanding filming schedules, and Natsume’s challenging heats. The narrative is set within the Omegaverse genre, specifically serving as a spin-off focusing on the characters who were not the primary couple in the main series, My Partner is a Purebred Omega. The story, which ran from August 2023 to September 2024, follows the unpredictable fate awaiting them as their professional and personal lives become increasingly intertwined.
