From childhood, Seong-yul has secretly admired Seungwon, his friend's older brother. However, the differences between them are significant—their age gap, their family backgrounds, and the harsh reality that Seungwon is an Alpha while Seong-yul is merely a Beta. One day, Seong-yul unexpectedly transitions into an Omega. With his job lost and urgent financial needs, things become even more dire when he learns that Seungwon is about to get married. Feeling utterly despondent, he resolves to enter a world where bodies are exchanged for pleasure. Just as he contemplates withdrawing, the overwhelming scent of Alpha pheromones and the way others gaze at him, reducing him to a mere object, makes him shudder... "You really thought spreading your legs for some random guy was a better option than leaning on me?" And at that moment, Seungwon appears—his first client. Seungwon is fully aware of what Seong-yul is—an Omega on the verge of selling himself for pleasure.
