Makoto Nanase has always been self-conscious about his appearance. He feels that he looks incredibly plain—the exact opposite of the almost supernatural cuteness his secondary sex, omega, is known for. To avoid judgment, he spends his daily life pretending to be a beta, a neutral secondary sex.

At the talent agency where he works, Makoto is assigned as the new agent for the model Rio Sakaki—both to his surprise and dismay. As an alpha, Rio has a natural urge that draws him to omegas, which he makes clear when he starts flirting with Makoto. However, as the two spend time together, Makoto begins to realize that Rio's claims of "love at first sight" may be more than just a pickup line.
