With the Alpha Childhood Friend I Despise

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](https://ridibooks.com/books/3587013383), [Naver Series](https://series.naver.com/comic/detail.series?productNo=13463251), [Lezhin](https://www.lezhin.com/ko/comic/hate_alpha_friend), [MrBlue](https://www.mrblue.com/webtoon/wt_000075160), [KakaoPage](https://page.kakao.com/content/68982989), [Toomics](https://www.toomics.com/webtoon/episode/toon/9082) R15: [RIDI](https://ridibooks.com/books/3587013395), [Naver Series](https://series.naver.com/comic/detail.series?productNo=13463589), [Bomtoon](https://www.bomtoon.com/detail/anabhorrentalpha), [Lezhin](https://www.lezhin.com/ko/comic/hate_alpha_friend_15), [MrBlue](https://www.mrblue.com/webtoon/wt_000075194), [KakaoPage](https://page.kakao.com/content/68983308), [Toomics](https://www.toomics.com/webtoon/episode/toon/9083)
