Seyeon was living a normal life when she suddenly became an 'Omega.' While still in disbelief caused by the unusual case, the doctor in charge brought photos of young and handsome men and showed it to Seyeon. Not just one, but many of them. "Whichever Alpha you like, I will match with you." Seyeon's luck for men unexpectedly escalated; she has never been in a relationship before, after all. In addition, the Alpha who clearly said that he will obediently wait for her decision was in fact a wild beast wanting to devour her. "Who will you choose, then? If it's not me, things will be very difficult for you."
