Synopsis: With My Hated Alpha Male Friend

When Sia opens her eyes in the emergency room, she hears something unbelievable — after living her whole life as a Beta, her genetic type has suddenly changed… she’s now an Omega. And her lifelong rival, Jihoon, suddenly starts acting suspiciously. Their relationship takes a dark turn as long-buried tension, desire, and obsession come to the surface — forcing Sia to face a truth she never wanted to acknowledge. **Original Webtoon:** R19: RIDI, Naver Series, Lezhin, MrBlue, KakaoPage, Toomics R15: RIDI, Naver Series, Bomtoon, Lezhin, MrBlue, KakaoPage, Toomics
