Yoon Ha-seong, a twenty-two-year-old beta, struggles as the bassist for an unknown indie band.
One day, after a failed performance and being dumped by his girlfriend, he runs into famous actor Go Ye-han. Ye-han

, claiming to be his fan, offers him a job and
connects him with a famous composer to learn composition.
Ha-seong actively supports him and treats him with affection.

Despite feeling a sense of unease, he finds himself drawn to Ye-han.
To repay the favor, he helps Ha-seong with his rut, which involves managing his pheromones.

"Huh, Ma-an... I'm not even an omega," he says.
"Ha-seong, you're overflowing with talent. You'd be better off with me than most omegas."

What started as a simple attempt to help him somehow leads to a rut partner.
And perhaps he shouldn't have ignored the vague sense of unease.

"It's true I wanted to have sex with you. But... is that really a problem?"
