Izumi is an ordinary beta who has inexplicably dated several alpha partners. After ending his latest relationship with an alpha, he begins to doubt his situation. While alphas typically hold higher social status, Izumi finds the dynamic unfulfilling and feels restricted by their dominance. Discussing his experiences with a beta friend at a bar catering to both betas and alphas, he is suddenly overcome by a floral scent.
