Aoi is a beta who always both admired and envied his older friend Shiki(alpha), who has now become his boss and his sex friend. But when Aoi's body begins to change to that of an omega as a result of repeated contact with an alpha, Shiki is the one to take him home and take care of him, keeping him there until his pheromones stabilize. However, Shiki has been in love with Aoi all along, and he recognizes that their current sex friends relationship has to come to an end before anything real can start. Trigger warning: forced confinement.

Airi Yamashita(beta→omega) is a driven career woman who just lost out on a promotion to the handsome Ren Kugayama who entered the company at the same time as her. But when they go out for an office drinking party, Airi totally loses control of herself and sleeps with Ren. The next morning, he tells her it's because of her omega pheromones, and sure enough, the doctor confirms that her gender has changed. Ren then offers to help her deal with her heats, but what he doesn't tell Airi is that she's his fated pair and he's noticed her pheromones for a long time. Trigger warnings: drunk sex, drug(roofie), attempted rape.
