I Became an Omega Trapped on a Deserted Island with the Obsessed Male Lead

I have to survive for a year, avoiding the obsessed male lead. I transmigrated into an explicit and decadent BL novel. As the villainess who envies and torments the beauty. And the deserted island is the place where the beauty and the obsessed male lead continue from the original story. Why am I trapped here too? There was an even bigger problem. In the original, I was a beta, but now I’ve manifested as an omega, and the beauty who was originally an omega has manifested as an alpha. It’s a complete mess. “Eve, I smell omega pheromones from you.” “If you come any closer, I’ll shoot.” The obsessed Alpha who hated me as if he wanted to kill me, smelled the pheromones and his eyes glazed over. The crazy guy is approaching, ignoring the gun. There’s no other choice. Bang!
