"What are you doing in my room?" I grimaced, my face scrunched up in a frown as I smell the strong pungent scent of Alphas. . . . In death's door waiting room with a person whom she thought was just a character in some Boy's love novel, she read and got sucked into the wrong world. Sick of her previous lavish life, sick of how her face has a permanent scowl, sick of how her voice sounded like, she finally has a shot at a normal life. But would the world really let her? Especially when the body she was in was from the destined Rival? . . . "An Omega? Hm..as far as I remember she was supposed to be a beta. Well, I suppose being an omega makes me a step closer to being normal." I smirked in satisfaction. . . .
