Reverse Omega

Seo Ha-Jun, an alpha, is always the center of attention and the subject of endless rumors in his department. The morning after getting completely drunk, he wakes up to a shocking pain in his lower body and the scent of an Omega. And the person responsible? None other than Oh Yun-U, an Omega surrounded by all kinds of unsettling rumors?! Refusing to accept that he was taken advantage of—especially by that Oh Yun-U— Ha-Jun decides to confront him... "Don't tell me you forgot about last night? Especially after leaving such a clear mark." (Source: Lezhin, translated)
