I’m Not an Omega

“There’s an Omega among us.” I was the twin sister of the sub-male lead in a dark, mature BL novel, more accurately, I was his Beta twin sister. The male lead of the novel I was transmigrated into was a madman who would destroy the sub-male lead right in front of the protagonist for so much as a glance. And here I was, pretending to be my brother at an academy filled with nothing but alphas after he ran away. “And I know who that Omega is.” The male lead’s crazed red eyes were fixed on me. He clearly had another problem with me. “So, I plan to mark that Omega today.” I felt the gazes of every alpha in the room turn towards me. “Anyone want to join me?” At the male lead’s words, the surrounding alphas began to rise from their seats, one by one. It seemed everyone finally knew. The original protagonist had finally awakened as an Omega! I stared at the protagonist, tense. But even he, his eyes flashing with a crazed light, approached me and said, “Gotcha. You can’t run away now, can you?” ‘Huh? Why me?’
